This is an Arduino Compatible Ultrasonic sensor, it can be used to measure the distance from the sensor to other objects around it. These types of sensors are used on robots for collision avoidance and guidance or as trip sensors for alarm systems or...

IR sensor tuned to 38KHz, perfect for receiving commands from a TV remote control. Runs at 3V to 5V, so it's great for any microcontroller. To use, connect pin 3 (all the way to the right) to 5V power, pin 2 (middle) to ground, and listen on pin 1. It...

The DHT22 is a basic, low-cost digital temperature and humidity sensor. It uses a capacitive humidity sensor and a thermistor to measure the surrounding air, and spits out a digital signal on the data pin (no analog input pins needed). Its fairly...
