The modules have the functions of low power consumption, an I2C communication interface as well as DSP algorithms to enhance the PIR sensor reliability. Such PIR products are widely used in applications such as security systems, automatic doors, intelligent lighting, garden lights, guest reception monitors, etc.

The HT7M21x6 series have an operating voltage range of 2.7V~5.5V and also contain a low current standby detection function and support both I2C or I/O interfaces. Other functions include an integrated temperature sensor, adjustable sensing sensitivity, fast warm-up function, etc.

The HT7M21x6 series include the HT7M2126, HT7M2136, HT7M2156 and HT7M2176 devices. Users can select the appropriate device according to their different horizontal and vertical viewing angles and different detection distance requirements for their specific applications.

This highly functionally integrated module series, in addition to allowing users to develop rapidly their PIR products, also provide a means for more flexible production and inventory management during the production process.
