This is a simple to use motion sensor. Power it up and wait 1-2 seconds for the sensor to get a snapshot of the still room. If anything moves after that period, the ‘alarm’ pin will go low.
This unit works great from 5 to 12V (datasheet shows 12V).
The alarm pin is an open collector meaning you will need a pull up resistor on the alarm pin. The open drain setup allows multiple motion sensors to be connected on a single input pin. If any of the motion sensors go off, the input pin will be pulled low.
We’ve finally updated the connector! Gone is the old “odd” connector, now you will find a common 3-pin JST! This makes the PIR Sensor much more accessible for whatever your project may need. Red = Power, White = Ground, and Black = Alarm.

Thank you for your email, you can but you would need to use something like an arduino or micro:bit that you have coded up to control this interaction. This is basically because the sensor needs something to read it's voltage which will drop when it detects movement thus allowing a micro controller like an arduino to turn outputs on and off.
Thank you for your email, it should read as an analogue input pulling high or low depending on if it is being triggered. You would need to write it as something like if Pin 0 Reads high then activate the out put as a very rough starting point. We don't have a particular resoruce around PIR sensors but the rest of our resources are on the link below
Hi Zal, I have contacted the supplier of the product and they unfortunately don’t have any information regarding your query. As such they have provide a copy of the datasheet, https://www.sparkfun.com/datasheets/Sensors/Proximity/SE-10.pdf, and advised that the only way to find out the max conditions is through testing. I’m sorry we couldn’t provide any further assistance with this.
Hi Avishka, The PIR sensor can run on a voltage between 5V-12V, for best results use a voltage above 6.7V. As such you wouldn’t need a voltage regulator unless you were using a voltage supply higher than 12V.
