Raspberry Pi Starter Kit Lesson 16: Raspberry Pi and PIR ...

04/07/2017· The PIR Sensor detection range is 812um and human body temperature radiates about 10um IR. So PIR Sensor is often used to detect human motion in alarm system. The PIR sensor in this projects has 3 pins (VCC, OUT, GND), 2 potentiometers (one for sensitivity adjustment and another for time delay adjustment) as showed in following picture.


Make a Rain Alert System with Raspberry Pi –

28/11/2017· You could also use an Arduino or Wemos, but a Pi will let us use GPIO Zero with Python and will be easier to extend later if we want to take it further ( sending tweets etc.).. To get an alert when it starts to rain, we’re going to rig this sensor up to a Raspberry Pi and trigger a buzzer. You could also have it blink LEDs, send you an SMS or tweet a photo of the washing line and the sky.

Interfacing a K30 CO2 sensor with a Raspberry Pi for ...

18/08/2017· sudo raspiconfig. Once the Pi is prepared to receive serial data, the K30 must be connected. This is a relatively simple case of connecting the K30 to 5v (a separate power supply was used), connecting the Pi and K30 to ground, and then crossconnecting the serial connections. A simple LED circuit was also established from the Pi’s GPIOs. To test the K30 sensor, a prototype as …
