M5StickC PIR Hat (AS312)

The M5StickC PIR Hat (AS312) is an amazing human body induction sensor that works perfectly with M5StickC. It's a 'Passive pyroelectric infrared detector' which can precisely detect infrared rays emitted by the human body. Once the infrared is detected, the sensor outputs a HIGH signal that lasts for two seconds until the next detection round. There's a 2 - second delay to note. This product has some great features. It has a detecting range of 150cm, a delay time of 2s, an induction angle of less than 100°, a standby current (IDDQ) of less than 60uA, and can operate in temperatures from -20 to 80 °C. The package includes 1 PIR Hat. It can be used in human body induction lamps, security products, and auto - induction systems. There are also official channels, a forum for support, and an Arduino example available.

Using the M5StickC PIR Hat is quite easy. First, connect it to your M5StickC device. When a person enters its 150cm detecting range, the sensor will sense the infrared from the human body and send a signal. Just remember there's a 2 - second delay between detections. As for maintenance, keep it in a dry place and avoid exposing it to extreme temperatures outside the -20 to 80 °C range. Also, don't let it get wet.
