Features:

  • AM312 Human Sensing Module: Based on passive body infrared technology digital intelligent automatic control products, high sensitivity, reliability, widely used in various types of automatic induction electrical equipment.
  • Low power consumption, small size, easy to install.
  • Internal use of digital signal processing, pit interference strong.
  • Repeatable trigger mode: that is, after the induction output is high, in the delay period, if the body in its induction range of activities, the output will remain high until the delay after the person to become Low level. (Ie, the sensing module automatically detects a delay period after each activity of the human body, and takes the last active time as the starting point for the delay time).
  • Working voltage: DC 2.7-12V;Static power consumption: <0.1mA;Sensing range: ≤100 degree cone angle, 3-5 m; (required depending on the lens) Working temperature: -20 to + 60 ℃
Wish I would have found these before getting HC-SR501 sensors.

Moderate sensitivity. Work very well with Esp8266 based projects and uses very little power.

Simple and good motion detector.

This is a small simple motion detector, it senses motion but does not have a delay or sensitivity like the larger ones. I do not need a delay as I am working with an Arduino so it handles any delays. I am using it as a presence detector for a TFT LCD display.

Great quality

love these little guys. very easy to hook up and very accurate

Great price and works great even at 3.3 volts

Very good price and the notion sensor works great. I connected it to a 8266 by espresiff

Worked well

I've tested and used one of these sensors already, and it worked well. Onyehn could have made things slightly easier and included the product specifications on their product page including the output current and voltages and the power supply range and polarity.

Works great!

Each one tested fine and I'll be happy to use them in my DIY products.

Low cost motion detect,, check!

good. BETTER. best Not high end performance but ok for small low cost projects
