]]>This temperature & Humidity sensor is a wired version of the DHT21, in a large plastic body. It 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 simple to use, but requires careful timing to grab data.
Connection:
This Sensor has 3 wires, connect these wires to your Arduino/Crowduino Project as following:
Sensor | Arduino/Crowduino |
---|---|
Red | +5V |
Black | GND |
Yellow | Digital I/O |
