Smart sensors are applied in multiple smart home scenarios such as smart switches (86 boxes), electronic temperature and humidity meters, smart curtain boxes, multifunctional smart sensors, smart door locks, smoke detectors, etc. The temperature and humidity sensor chip provides core hardware for electronic temperature and humidity meters with the advantages of high precision, low power consumption, small size, and high cost-effectiveness. It can accurately monitor indoor temperature and humidity data and link with air conditioning/humidifiers to maintain a comfortable environment. Multi functional intelligent sensors integrate human body, temperature and humidity, lighting, etc., which can be linked to energy saving (such as turning off air conditioning when people walk) and alarm (such as vibration and anti pry). The multi-channel buttons and touch panel of the smart door lock need to control multiple LED backlight scenes, and the interface chip of Zhongke Yinhe chip can be used to achieve GPIO interface expansion requirements.
