Q:
Hi, are you able to use the motion sensor to activate an LED light / lamp? This creating a motion sensor activated light
A:
Hi Ben,
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.
Best Regards
Cullen

Q:
I recently bought the PIR motion sensor to use with micro:bit. Please advise what is the signal it will give out (0/1 for off/on?) and which block coding I shall use? Can you give me a block coding example? I am a beginner of micro:bit. Thank you.
Asked by: Rico
A:
Hi Rico,
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

Q:
Are you able to use this motion sensor as an activity tracker? If so, could you link it to a vibrating motor?
Asked by: Arun Sharma
A:
Hi Arun, The PIR Motion sensor wouldn't really be any good for an activity tracker. The sensor works by triggering the alarm pin to go low when the sensor detects a change in the area it can see, for instance someone walking in front of the sensor while it is positioned in a room. As such if you used this as an activity tracker not only would it constantly be set off but also the surrounding environment would be constantly changing and it wouldn't be able to correct identify when the sensor needs to be triggered.

Q:
Hi there. I bought this to work with a BBC Microbit. I'm not sure what to solder to get it to operate at 3V and then power it via the microbit? Alternatively I was thinking of powering it separately with 6V and then wiring the alarm lead to an input on the Microbit but worried that the alarm would be putting too much voltage into the Microbit? Any advice or links to suitable guides would be much appreciated... as you may gather my electronics knowledge is very basic. I'm still trying to get up to speed to work on electronics projects with my 10 year old daughter :)
Asked by: Mark
A:
Hi Mark, The PIR sensor can run to 3.3V so just over what the micro:bit can handle. As such your better running this from a separate supply, or running this from a supply and then regulating this to 3V for the micro:bit, either would work. You would then connect the alarm pin onto the micro:bit, as this will go from high to low when trigger and you would then code the micro:bit to detect this. You may need to use a pull-up resistor, 10K would be fine, however the micro:bit should have this built in.

Q:
Hello I just want to know the reach and the angle coverage of the sensor?
Asked by: Zal
A:
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.

Q:
hi! how can i use this without a voltage regulator and what voltage should i use?
Asked by: avishka
A:
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.

Q:
Do you sell a connector for the PIR Module female connector and if yes, what is its product code?
Thank you
Thank you
Asked by: stephen wright
A:
The PIR Module can be connected with the jumper wires we stock either male to male or male to female.4130-jumper-wires-premium-mm-pack-of-10 or 4129-jumper-wires-premium-mf-pack-of-10

Q:
Hi I want to use your PIR Motion Sensor with the GENIE C08 PIC board, what is the best way to connect it to this board?
Asked by: Martin Cassidy
A:
I've added another image, just under the main product image that shows how to do this. You need a pull up resistor and watch out as the colours of the wires are not quite as you would expect in that the black wire isn't zero volts.
