SHT21 Humidity and Temp Sensor
Product description
Description:
To optimize accuracy of temperature and humidity readings, the SHT21 sensor is placed at the tip of the board, isolating it from heat producing circuitry. Two of the sensor?s four pins are ground and +5V; the other two are clock and data pins that make up the 2-wire serial interface. The board is 5V tolerant and designed to operate directly off the supply voltage coming from the Arduinos.
The sensor can be placed in soil to measure moisture and temperature, which makes it ideal for using it in a garden or greenhouse. The humidity sensor is also especially useful in building remote weather stations.
Specifications:
Energy consumption: 80 uW (at 12 bit, 3V, 1 measurement/s)
Relative Humidity operating range: 0-100% RH
Relative Humidity resolution of 0.03%
Relative Humidity Response Time of 8 sec (tau 63%)
Temperature operating range: -40 to +125°C
Temperature resolution of 0.01 C
4 pins: +5V, GND, Clock (SCL), Data (SDA)
Bidirectional communication over a single pin on I2C protocol
Board is 5V tolerant, allowing sensor to run from a 5V supply on Arduinos I/O pins
