BM25S2021-1
DESCRIPTION

The BM25S2021-1 is a high-precision, low-power, and cost-effective temperature and humidity digital sensor. The product is calibrated in factory to guarantee the measurement results are in high consistency. With the featured signal processing circuit and algorithm, the measurement data has extremely high stability and accuracy. The humidity data has been temperature-compensated, it can be used directly without secondary processing.

The product has 4 pins which include 2 power pins (VDD, GND) and 2 communication pins. The I2C interface and one-wire communication can be chosen to read data from the sensor. The I2C communication protocol uses the CRC-16 mechanism to ensure correct data transmission. The BM25S2021-1 is suitable for applications in temperature and humidity measurement, monitoring, and other related products, such as dehumidifiers, heating and cooling air conditioners, and Internet of Things applications.
