With thousands of electronic components available in the market, it just seems too complicated and cumbersome. We strive to make electronics easier, accessible, clutter-free for Novices and Advanced users. You could be an advanced user like a professional lab engineer, electronic major student, experienced hobbyists, or a novice user who doesn't have much electronics knowledge. Fear not, we got you both covered. As our tagline suggests - "The Last Piece of the Puzzle or Maybe the First" Specifications Working voltage range: DC 4.5V 20v Current drain: <60ua Detection range: <140 degree Voltage output: high or low level Color: white plus green Delay time: 5 to 200s Blockade time: 2.5S Work temperature: 20 plus 80 degree This function can be achieved inch sensor output time inch and inch blocking time inch interval between the work can be applied to interval detection products While this feature can effectively inhibit the load switching process for a variety of interference; This time can be set to zero seconds tens of seconds. Compatible with Arduno, raspberry pi, avr, pic, 8051, etc. Robodo SEN3 Hc Sr501 Pyroelectric Infrared Pir Motion Sensor Detector Module for Arduino AVR Description The pir sensor module allows you to sense motion. It is almost always used to detect the motion of a human body within the sensor's range. It is often referred to used inch pir inch, inch pyroelectric inch, inch passive infrared inch and inch ir motion inch sensor. The module has an onboard pyroelectric sensor, conditioning circuitry and a domb shaped Fresnel lens. With induction blocking time (default setting: 2.5S block time): sensor module output every time after induction (high variable to the low level), you can set up a blockade followed by time period, during this time period does not accept any inductive sensor signals. Features This function can be achieved inch sensor output time inch and inch blocking time inch interval between the work can be applied to interval detection products.

This module works on 5V DC. **Q: i have purchase one but there is no connection details vcc gnd and o/p** A: Hi, Simply google "hc-sr501 pir motion sensor connection" and go on image search. We would have shared the datasheet with you but unable to attach any document while replying. **Q: Can i get 12 volt output, if input is 12 volt?** A: Yes you can. Be sure to use the regulated supply through 3 terminal regulator like 7812 or LM 317. Power supply should be ripple / noise free for this module to get maximum performance. ## Customer Reviews ### ⭐⭐⭐⭐⭐ It is good but may think any heat source to be a human *by S***U on 31 January 2023* The product is good but the problem is that it can detect any heat source as a human but it is not their fault this was designed that way it even beeps from a little heat or radiation from a monitor so If you manage to keep hot things away from your project then go for it ### ⭐⭐⭐⭐ Four Stars *by D***Y on 1 August 2018* Nice Product ### ⭐ Defective product.
