Re: IR Tracking Sensor (TCRT 5000 ) always gives led off as output

So it looks like the best range you can get is when your sensor is operating at 5v but we cant put 5v from the output pin directly on to the gpio as it will damage your pi. so we need to use a potential divider circuit like this. https://i.imgur.com/HN2u7aw.jpg that will limit the voltage applied t...

Re: IR Tracking Sensor (TCRT 5000 ) always gives led off as output

I think shantannunandan is probably working off the specification provided by the seller. Specifications and Features : Working voltage: DC 3.3V-5V. Working current: ≥ 20mA. Operating temperature: -10℃~+50℃. Size : 30 x 16 mm. Detection distance :2 - 40 cm. <<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<< you may...

Re: IR Tracking Sensor (TCRT 5000 ) always gives led off as output

Hi. Please post a link to the sensor you have or were you got it from, so we can see what its specifications are. The way you have it wired up makes no sense with resistors on the supply ground and output connections, I suspect this device is a 5v device with a 5v output signal, which means you nee...

IR Tracking Sensor (TCRT 5000 ) always gives led off as output

I am using a Raspberry PI3 Model B and TCRT 5000 sensor to monitor movement. I am using a Python script(Python3) to read the data from the sensor. Script used - Code: Select all #!/usr/bin/env python import RPi.GPIO as GPIO TrackPin = 11 LedPin = 12 def setup(): GPIO.setmode(GPIO.BOARD) # Numbers GP...
