Witty Fox – SI7021 Humidity Temperature Sensor Breakout Board

Witty FoxSi7021 humidity temperature sensor offers better accuracy and a wider range for temperature and humidity readings, as compared to DHT11 and DHT22. It also comes in a significantly smaller r size as compared to the former 2 sensors.The Si7021 has 0.4 C temperature accuracy at a range of -10 to +85 C and 3% relative humidity measurements with a range of 080% RH. This sensor is perfect for environmental monitoring projects and uses the I2C interface for data transfer which makes it compatible with the majority of available microcontrollers.

The Si7021 temperature and humidity sensor offer an accurate, low-power, factory-calibrated digital solution ideal for measuring humidity, dew-point, and temperature, in applications ranging from HVAC/R and asset tracking to industrial and consumer platforms.e. It can be used as hardware and software-compatible drop-in upgrades for existing RH/ temperature sensors.
