Grove-Temperature & Humidity Sensor Pro is a high accuracy temperature and humidity sensor based on the DHT22 module (also known as AM2302 or RHT03). High-cost performance and high precision ma...

The resistance of a thermistor will increase when the ambient temperature decreases. It’s this characteristic that we use to calculate the ambient temperature. The detectable range of this sensor i...

The sensor(chip) used in the module is designed with Sensirion’s CMOSens® technology. The chip is well calibrated, linearized and compensated for digital output. The typical accuracy of this module...

The main component of the module is a simple microphone, which is based on the LM386 amplifier and an electret microphone. This module’s output is analog and can be easily sampled and tested by an ...

Most ultrasonic distance sensors aren't waterproof which can be a problem if you need your project to withstand the elements outdoors. No need to worry any more! This is a waterproof & ultrason...

This is a multifunctional sensor that gives you temperature and relative humidity information at the same time. It utilizes a TH02 sensor that can meet measurement needs of general purposes. It pr...

The RCWL-0516 is particularly suitable as an alternative to using a PIR motion sensor. When it detects a moving object, the output changes from a low logic level to a high level (3.3 volts). Approp...

It has only three terminals and operates on 5 V power supply. Vdd= + 5 Vdc, GND= ground, OUT= TTL signal output

Ultrasonic sensors emit ultrasonic pulses, and by measuring the time of ultrasonic pulse reaches the object and back to the transducer, the distance of sensor from the target object is calculated. ...
