PIR sensors
Not anyone, a sensor that generates a signal when I come close to the car, I rather it not be IR since, AFAIK, they need to be in specific positions to work, unlike NFC or Bluetooth that cover areas around the sensor.
Basically I'm trying to create a smart switch that goes on or of based on whether I'm close (in the range of 10-20 feet) to it or not.
Thanks again, learned a lot... I decide to give a try there, I also had a look on some components' datasheet and seems to be what I need... Let's see, if end up getting the boards I'll publish a review here later.
Hi @Siddharth-Velappan
The warmup time of the MH Z19b is 3 minutes. So 2 is probably fine, but you could probably do 3 just in case. Although 2 would save your more battery time.
Do you mind explaining your setup a bit more? I would love to do something similar but I do not know where to get started with the PIC microcontroller!
