Using the WeMos D1 to gather temperature, pressure, and humidity readings from DHT11, light intensity sensor TSL2561 and TMP180 sensors. Also calculates the speed of sound from the collected data. The WiFi RSSI is also collected and displayed.
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
