My IoT Projects - What I Built Over Time

AC.balcony - Measures temperature, humidity, soil moisture, brightnessy and atmospheric pressure. Controls balcony plants watering system supplied from container.
AC.camper - Measures temperature and humidity in the camper van parked outside in the yard. Sends alarms from two motion sensors.
AC.clock - RGB LED ring showing time as lit pixels, adapted to ambient brightness. Gets time updates via MQTT.
AC.gardenControl - Measures inside temperature, inside humidity, outside temperature, outside humidity, and soil moisture at our garden plot about 2km from home. Controls watering system supplied from ground water pump. Connected via mobile internet WLAN router.
AC.gardenPower - Controls outside and inside lighting of the hut on our garden plot. Uses motion sensors to control outside lighting and send alarms.
AC.power - Switches up to 8 power outlets on and off. I am using a number of these throughout to house to, in example, control lighting.
AC.signal - Controls a full size train signal replica (showing symbols "off", "full ahead", "slow ahead", "stop")
AC.ticker - A LED ticker tape. Text and speed can be controlled remotely.

Plans:

AC.balcony 2.0 - Wind sensor (direction, strength) and a rain gauge
AC.kitchen - Report on stove plate and fridge temperature
AC.power - Add temperature reporting to control the temperature in the camper van and garden plot hut, using an electric heater
AC.train - Controls my G-gauge garden train. Instead of supplying power and DCC control through the rails (which I found to be very flaky due to oxidation of the rails outside), the trains get powered by rechargeable batteries and controlled through MQTT via WLAN. An older prototype based on a 433GHz radio connection and a proprietary protocol is already working.
