Thanks Nicholas Wilde. Internal measurements from a Raspberry Pi running piaware.
Air and soil temperature in the hoop house. Raspberry Pi and a DS18B20 temperature sensor.
Uses Raspberry Pi with Dallas DS18B20 sensors and BMP180 for pressure. Uses udp comms to Wemos D1 mini for switching relays for pump and pond heater. Monitors Koi pond temperature and shack (with water pipes in loft) sending email and ThingTweet update
The data from raspberry pi connected to Arduino with MQ sensors to measure air quality in my area.
Multiple Wemos D1 Minis with Dallas ds18b20 sampling temperatures updating via UDP over local network to Wemos D1 Uno board for tx to Thingspeak. Raspberry Pi triggers D1 when to tx over udp as Wemos has no time clock. Propagator Wemos monitors temper
