Overview
BF32 is a brand new product equipped with a dedicated ASIC sensor chip, a high-performance semiconductor silicon-based capacitive humidity sensor and a standard on-chip temperature sensor, and is connected with a high-performance 8-bit microcontroller to output standard I2C data signals. At the same time, each sensor is calibrated in a high-precision temperature and humidity verification box, so the product has good consistency; BF32 products use special humidity-sensitive materials, so that their performance is extremely stable in high-temperature and high-humidity environments. It has the advantages of fast response, strong anti-interference ability, and high cost performance.
