Model Name/Number | ds18b20 temperature sensor probe (waterproof) |
Usage/Application | Industrial |
This is a 1 Meter Long Waterproof, sealed and pre-wired digital temperature sensor probe based on DS18B20 sensor. It is very handy for when you need to measure something far away, or in wet conditions. Because they are digital, you don't get any signal degradation even over long distance.
These 1-wire digital temperature sensors are fairly precise (±0.5°C over much of the range) and can give up to 12 bits of precision from the onboard digital-to-analog converter. They work great with any microcontroller using a single digital pin, and you can even connect multiple ones to the same pin, each one has a unique 64-bit ID burned in at the factory to differentiate them. Usable with 3.0-5.0V systems.
The only downside is they use the Dallas 1-Wire protocol, which is somewhat complex, and requires a bunch of code to parse out the communication. When using with microcontroller put a 4.7k resistor to sensing pin, which is required as a pullup from the DATA to VCC line.

The VL53L0X is a time-of-flight ranging system integrated into a compact module. The VL53L0 uses ST’s FlightSense technology to precisely measure how long it takes for emitted pulses of infrared laser light to reach the nearest object and be reflected back to a detector, so it can be considered a tiny, self-contained lidar system. This time-of-flight (TOF) measurement enables it to accurately determine the absolute distance to a target without the object’s reflectance greatly influencing the measurement. The sensor can report distances of up to 2 m (6.6 ft) with 1 mm resolution, but its effective range and accuracy (noise) depend heavily on ambient conditions and target characteristics like reflectance and size, as well as the sensor configuration. (The sensor’s accuracy is specified to range from ±3% at best to over ±10% in less optimal conditions.)
Ranging measurements are available through the sensor’s I2C (TWI) interface, which is also used to configure sensor settings, and the sensor provides two additional pins: a shutdown input and an interrupt output.
The VL53L0X is a great IC, but its small, lead less, LGA package makes it difficult for the typical student or hobbyist to use. It also operates at a recommended voltage of 2.8 V, which can make interfacing difficult for micro controllers operating at 3.3 V or 5 V. Our breakout board addresses these issues, making it easier to get started using the sensor, while keeping the overall size as small as possible.

GY-53 VL53L0X Laser ToF Flight Time Ranging Sensor Module can be used for easy integration into your devices and basic gesture detection applications. Thanks to its 2.8V regulator and level shifters, the VL53L0X satellite board can be used in any application with a 2.8 to 5V supply.
The VL53L0X is a Time of Flight distance sensor like no other you’ve used! The sensor contains a very tiny invisible laser source and a matching sensor. The VL53L0X can detect the “time of flight”, or how long the light has taken to bounce back to the sensor. Since it uses a very narrow light source, it is good for determining the distance of only the surface directly in front of it.
Unlike sonars that bounce ultrasonic waves, the ‘cone’ of sense is very narrow. Unlike IR distance sensors that try to measure the amount of light bounced, the VL53L0x is much more precise and doesn’t have linearity problems or ‘double imaging’ where you can’t tell if an object is very far or very close.
The PCB section supporting the VL53L0X module is perforated so that developers can break off the mini PCB for use in a 2.8V supply application using flying leads. This makes it easier to integrate into development and evaluation devices due to its small form factor.
The module is designed for low-power operation. Ranging measurements can be automatically performed at user-defined intervals. Multiple thresholds and interrupt schemes are supported to minimize host operations. Serial port and PWM to read the data code: STM32, Arduino, 51 MCU.
Note that due to the infrared will be affected by the outside light, in the light will affect the maximum range of measurement, will not affect the measurement accuracy. Default configuration: serial baud rate 9600, automatic output, high precision mode. When using, please remove the sensor film.
VL53L0X Overview:The VL53L0X is the latest product based on ST’s patented FlightSense™ technology. This is a ground-breaking technology allowing absolute distance to be measured independent of target reflectance. Instead of estimating the distance by measuring the amount of light reflected back from the object (which is significantly influenced by color and surface), the VL53L0X precisely measures the time the light takes to travel to the nearest object and reflect back to the sensor (Time-of-Flight). Combining an IR emitter and a range sensor, the VL53L0X is easy to integrate and saves OEMs long and costly optical and mechanical design optimizations.
Note: The VL53L0X is delivered with a liner, in order to prevent potential foreign material to penetrate inside the modules holes during the assembly process. It must be removed at the latest possible step during final assembly, and anyway before module calibration.

An H-Bridge is a circuit that can drive a current in either polarity and be controlled by Pulse Width Modulation (PWM).
Pulse Width Modulation is a means of controlling the duration of an electronic pulse. In motors try to imagine the brush as a water wheel and electrons as the flowing droplets of water. The voltage would be the water flowing over the wheel at a constant rate, the more water flowing the higher the voltage. Motors are rated at certain voltages and can be damaged if the voltage is applied to heavily or if it is dropped quickly to slow the motor down. Thus PWM. Take the water wheel analogy and think of the water hitting it in pulses but at a constant flow. The longer the pulses the faster the wheel will turn, the shorter the pulses, the slower the water wheel will turn. Motors will last much longer and be more reliable if controlled through PWM.

This is an easy to use digital soil moisture sensor. Just insert the sensor in the soil and it can can measure moisture or water level content in it. It gives a digital output of 5V when moisture level is high and 0V when the moisture level is low in the soil.
The sensor includes a potentiometer to set the desired moisture threshold. When the sensor measures more moisture than the set threshold, the digital output goes high and an LED indicates the output. When the moisture in the soil is less thatn the set threshold, the output remains low. The digital output can be connected to a micro controller to sense the moisture level. The sensor also outputs an analog output which can be connected to the ADC of a micro controller to get the exact moisture level in the soild.
This sensor is great for making water gardening projects, water sensing, etc.

But instead of sniffing the blackbody radiation from a moving person, this sensor uses a microwave Doppler radar technique to detect moving objects. It has a sensitivity range of ~7 meters. When triggered, its TTL-level output (OUT) pin will switch from LOW (0 V) to HIGH (3.3 V) for a finite time (2 to 3 s) before returning to its idle (LOW) state.
This flexible sensor module can easily be used in conjunction with many microcontrollers and even without a microcontroller at all. It can handle power supply inputs anywhere from 4 to 28 V.
The output pin can be utilized for a multitude of tasks, such as for driving an aural/visual indicator or even linking with the I/O of any 3-V microcontroller for further processing. During construction, avoid any metal part in front of the sensor module. Similarly, always keep a minimum of 1-cm clear space on the front and rear side of the module.

A load cell is a transducer that is used to create an electrical signal whose magnitude is directly proportional to the force being measured. The various types of load cells include hydraulic load cells, pneumatic load cells and strain gauge load cells.
This is a standard load cell for measuring weight upto 5 Kg. The output of the load cell is in mili-volts and cannot be directly measured by a micro-controller. So an ADC with high resolution or an instrumentation amplifier is required to make the output of the load cell readable to a micro-controller.
