Send humidity & temperature sensor readings to Initial State from a Raspberry Pi
Rich Plakas has written a great tutorial on using the simple DHT22 temperature/humidity sensor with the Raspberry Pi in which he sends the readings to online IoT dashboard provider Initial State. He borrows a lot from other code (which he…
Enviro pHAT reviewed and used with the Raspberry Pi and the Initial State dashboard
Jamie Bailey has written a great review of Pimoroni’s Enviro pHAT. He’s evaluated the sensors on-board and has then integrated them, using Python, with the Initial State dashboard. He’s used the temperature sensor and accelerometer to provide data and has…
Raspberry Pi home automation stops fumbling in the dark (more’s the pity!)
The bloggers over at WhiskeyTangoHotel have been investigating home automation solutions. They’ve come up with a Raspberry Pi-based solution which detects, via Bluetooth, the presence of a device (in this case an iPad) and switches on some LEDs to save…
Create an attendance system using RFID and a Raspberry Pi
Over at Circuit Digest, Saddam has written a tutorial that helps you to create an attendance system based on RFID cards and a reader. The code is written in C and Saddam takes you through it all so you understand…
Calculate true North using a Raspberry Pi, a GPS and a compass
CodeGirl42 has written a very comprehensive tutorial that teaches you all about GPS and taking magnetic North bearings using a magnetometer. There’s a lot of maths involved, but she takes you through it and then creates a C++ script to carry…
