We have a Dakboard digital calendar in our kitchen — showing lots of house and temperature data. So naturally; it must show the actual outdoor temperature as well. To do this I used a Raspberry Pi 2, …

I made a simple HAT (Hardware Attached on Top) for the Raspberry Pi to read multiple DS18B20 temperature sensors — it was surprisingly easy. I used the measured temperatures to control a fan using …

Temperature sensor with serial RS-485 interface. Two additional sensors can be connected using 3-pin headers on the circuit board. Uses an AVR ATmega8 microcontroller.

I rebuilt an existing interface module — to be a stand-alone temperature and humidity sensor, with serial RS-232 interface. Uses an AVR ATmega8 microcontroller.

I rebuilt an existing interface module — to be a stand-alone temperature and light sensor, with serial RS-232 interface and some signal LEDs. Uses an AVR ATmega8 microcontroller.

Light intensity and temperature sensors; with white, green, yellow, red and blue signal LEDs and a buzzer. RS-232 communication. Uses an AVR ATmega8 microcontroller.

Reads temperature and controls a fan using a PWM output, fan and alarm set point can be adjusted and is shown on a LCD. Uses an AVR ATmega8 microcontroller.
