- The IR sensor itself is housed in a hermetically sealed metal can to improve noise/temperature/humidity immunity.
- Size: Rectangular
- Output: Digital pulse high (3V) when triggered (motion detected) digital low when idle (no motion detected). Pulse lengths are determined by resistors and capacitors on the PCB and differ from sensor to sensor.
- Sensitivity range: up to 20 feet (6 meters) 110° x 70° detection range
- Power supply: 5V-12V input voltage for most modules (they have a 3.3V regulator), but 5V is ideal in case the regulator has different specs
Running LED or Johnson counter module of 25 LEDs designed using 4017 IC. Programming is not required for the working. Module can be worked using astable multi vibrator designed using 555 timer IC. Watch the video demonstration to get the working of module.
