For when you’re too lazy to simply close the lid.
When the piicodev sensor detects proximity within 100 mm, my Python script publishes a message to my MQTT broker, subscribed to by a script on my computer. This script triggers a command to send to computer to sleep.
Next step is to figure out how to put my computer to sleep when I’ve been away from the desk a little while.
I used the paho-mqtt python package, mqtt in a docker container, and it’s all running off a Raspberry Pi.
Very interesting use of a PiicoDev Distance Sensor.
Thanks for sharing.
Very elegant and great experiment!
I watched an interesting video recently on the difference between a motion sensor and actual human detection and came across this sensor: mmWave Radar - Human Presence Detection | DFRobot SEN0395 | Core Electronics Australia
I’m keen to see how you go!
Hi Liam. The human presence detection looks interesting. A range of 9 m would work in most living areas and I could see it used in home automation set ups.
