10pcs AM312 Mini PIR Motion Sensor Module Pyroelectric Human Infrared IR Distance Detector
About this item
- 【AM312 Human Sensor Module】It is a digital intelligent automatic control product based on passive human infrared technology, with high sensitivity and reliability, widely used in all kinds of automatic sensor electrical equipment.
- 【Features】Enhanced anti-interference, internal digital signal processing, direct high and low level output.
- 【Widely Applications】Security Products, the human body sensors toys, the human body sensor lighting, industrial automation and control, etc.
- 【Specific Parameters】Working voltage: DC 2.7V - 12V; Static power consumption: <0.1mA; Delay time: 2 seconds, blocking time: 2 seconds; Trigger mode: repeatable; Sensing range: less than or equal to 100 degrees cone angle, 3 - 5 m (depend on the specific lens); Working temperature: -20 degrees Celsius to +60 degrees Celsius.
- 【Repeatable Trigger Mode】The induction output high level, in the delay time period, if there is a human body in its sensing range of activities, its output will remain high until the person leaves the delay, only to become low level (Ps: the induction module detects the human body's every activity will be automatically postponed after a delay time period, and the next activity time for the start of the delay time).

I wrote to Bigamart's customer support and they accompanied the process of reshipping the item until it finally arrived. I felt a genuine effort to solve the problem till it was finally solved.
The package was here in Australia from England in a few days — so quick! Something was missing and they refunded it straight away. Pretty happy with these guys.
