Several sound pressure level values (preprocessed by our embedded measuring device) are plotted
Thanks Nicholas Wilde. Internal measurements from a Raspberry Pi running piaware.
Wemos D1 Mini TCP server with Dallas ds18b20 sampling temperatures updating via TCP over local in each location Raspberry Pi5 calls for temperature every 30 minutes (crontab), writes to a MySQL database and sends to Thingspeak.
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
