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.

Pomiar temperatury w domu i na zewnatrz. ESP-01+DS18B20. 16-10-2021 - wysyłamy dane do TS tylko w przypadku zmiany wartości.

Meranie vykonávajú mikrokontroléry s čipom ESP8266-12 pomocou snímačov DS18B20.

ESP8266 Lua NodeMcu Amica CP2102 WIFI modul. Od 1.1.2019 druhá jednotka ESP na kanálu 666580

Temperatura w krośnie + inne czujniki

Temperature data from a DS18B20 sensor connected to an ESP32. This channel monitors fridge temperatures in real time and logs them for historical analysis.

This project monitors six DS18B20 temperature probes. The data is collected via an ESP8266 NodeMCU micro controller.

A NodeMCU with 3 DS18B20 monitors the temperatures (T[o, T[u]) of a storage tank, heated by a combination of Heat pump, wood boiler and solar panels. IT also Monitors the temperature of the wood boiler (T[HV]), the temperature of the exhaust gas (T[Ag]

Recepcion de parametros del sensor DHT22 y DS18B20

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
