Review on π Onyehn IR Pyroelectric PIR Motion Sensor Modules - Pack of 2pcs | DC 2.7 to 12V Detector for Infrared Detection by David Golden
Data output voltage lower than expected
I read the data sheet before ordering. I was expecting 3V data high but I only get 1.6V for high. I checked with an oscilloscope that there were no on/off cycles. It has a stable output voltage of 1.67. I checked both sensors, both work the same. Besides method validation and test results, I had other PIRs. They fire and work well, but that power is a bit low to use like I wanted, so go to the parts cart. Can be quite good for low power applications.
- AM312 human detection module: based on body passive infrared technology, digital intelligent automatic control products, high sensitivity, reliability, widely used in various types of automatic induction electrical equipment.
