ESPHome based PIR motion sensor setup | Malachi Soord

PIR Motion Sensors. PIR motion sensors, albeit called sensors, are configured as switches in Tasmota since they basically report motion ( 1) or no motion ( 0) to the device. Most PIR's are single wire and they require connecting to VCC, GND and one GPIO. In this guide we will use GPIO13 as the pin that the PIR output is connected to.

PIR am312 | MySensors Forum

@Nca78 said in PIR am312: Not sure if 2 AA/AAA is the best solution, I would go for lithium cells. CR2032 would probably have too short battery life in a busy room (somewhere around 6 months) but bigger cells like 2477 or CR123 (>1000mAh) would last way over 1 year.

Project AM312 and Sonoff R2 - Tasmota

Project AM312 and Sonoff R2. This use case represents a method to use AM312 as a "wave hand toggle" (for under-cabinet kitchen LED). Please note that this solution isn't working in 100% (this sensor has a detection range of a few meters, to decrease the range you can remove the lens from the sensor but still it will pick up movement from 50 cm.

AM312 PIR issues – halfforked – IoT stuff

Jun 16, 2018· AM312 PIR issues. Not long after making my BRUH multisensors I realized I had to modify one to have 2 PIR sensors. Editing the code I managed to do just that. PIR installed. Tested and works great. It’s a multisensor in middle of a corridor with 2 AM312s pointing in opposite directions. About a month later one of the PIRs started to have ...

AM312 PIR Sensor with ESP8266 - reddit

AM312 PIR Sensor with ESP8266. Vcc is 3,26V directly off a WEMOS D1 board. When motion is detected the sensor outputs 3,26V which can be interpreted as a high on the esp8266. But when the sensor is low, it still gives 2,4V which is too much to be interpreted as a low. I have seen other people use it directly without diodes or such.
