SI7021 sensor
Information
The Si7021 I2C Humidity and Temperature Sensor is a monolithic CMOS IC integrating humidity and temperature sensor elements, an analog-to-digital converter, signal processing, calibration data, and an I2C Interface. The Si7021 offers 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.
Features
- Precision Relative Humidity Sensor ± 3% RH (max), 0–80% RH
- High Accuracy Temperature Sensor ±0.4 °C (max), –10 to 85 °C
- 0 to 100% RH operating range
- Up to –40 to +125 °C operating range
- Wide operating voltage – (1.9 to 3.6 V)
- Low Power Consumption – 150 μA active current
Setup
In order to use the SI7021 sensor use the following settings:
Mandatory
Hardware : SI7021 sensor
Types : humidity, temperature
Address : <I2C Address>,[I2C Bus] where the I2C bus is optional
Ex: 0x40
Other settings can be found at the sensor setup information
