Witty Fox - SI7021 Humidity Temperature Sensor Breakout Board

Witty Fox Si7021 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 0–80% 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.

FAQ

1. What is SI7021 Humidity Temperature Sensor?

The SI7021 I2C Humidity and Temperature Sensor is a monolithic CMOS IC that integrates humidity and temperature sensing elements, an A/D converter, signal processing, calibration data, and an I2C interface. The use of patented, industry-standard, low-k polymer dielectrics for moisture sensing enables the construction of monolithic CMOS sensor ICs with low power consumption, drift and hysteresis, and excellent long-term stability. increase. The humidity and temperature sensors are factory calibrated and calibration data is stored in on-chip non-volatile memory. This allows the sensor to be completely replaced without the need for recalibration or software changes.

2. How to use a SI7021 Humidity Temperature Sensor?

The Si7021 is a low-cost, easy-to-use, highly accurate digital temperature and humidity sensor. It only requires two wires for I2C communication and can also take relative humidity readings and accurate temperature readings. This sensor is ideal for environmental sensing and data collection, ideal for weather stations and humidor control systems. The Si7021 also features a hydrophobic PTFE filter that covers the sensor inlet. This filter blocks contaminants but allows water vapor to pass, protecting the sensor from water damage and providing accurate sensor readings.
