5PC Si7021 -21 SHT21 HTU21 Digital Humidity Temperature Sensor Module2168
The humidity and temperature sensor board that carries a digital SHT21 humidity and temperature sensor from Sensirion.
The SHT21 uses a capacitive sensor elements to measure humidity, while temperature is measured by a band space sensor. Both sensors are perfectly coupled to a 14-bit ADC, which then transmits the digital data via the I2C protocol.
It has a 4-pin interface that can communicate directly with the analog pins
Bidirectional communication over a single pin on I2C protocol
Board is 5V tolerant, allowing sensor to run from a 5V supply on I/O pins
colour:Blue
Material:Electronic component
size:Approximately 1.3 x 1cm
Package Contents:
5 x HTU21D Temperature & Humidity Sensor
