Arduino Pro Mini ATmega328 @ 3.3V 8M. ESP8266-01 WiFi Module. DHT21 (AM2301) Digital Temperature Humidity Sensor Module. Accuracy: 0.1 Measurement range: 0-100%RH Precision: ±3%RH. Temperature measurement range: -40℃ ~ +80℃. Precision: ±0.5℃

Example channels from Fun with Arduino course

I'm experimenting with the ESP8266 WiFi-UART adapter and found some code showing how to use it as the bridge between a temperature sensor and ThingSpeak. Based on code at http://www.instructables.com/id/ESP8266-Wifi-Temperature-Logger/.

Arduino Based System used to monitor the inside temperature and humidity of an outside Food freezer. Ambient, in this case outdoor, temperature and humidity is also collected.

Arduino, XBee and DHT11 Based Thermostat Prototype. Measuring the temp/humidity inside my home and temp/humidity in the wet side of the air handler.

Данные о погодных условиях теплицы и окружающей среды

Este sistema te permite monitorear en tiempo real: La temperatura del ambiente (°C) El nivel de humedad del aire (%) ☀️ El nivel de luminosidad (día/noche) ???? Si hay personas cerca del poste Los datos se actualizan automática

Monitoramento de Temperatura e umidade e disparo de alarme com com Esp32 utilizando Sensor DTH11 e PIR - IOT

THINGSPEAK_TEST

Este canal almacena datos de sensores de calidad del aire en tiempo real.

Currently, this LoLIn Nodemcu is used to measure the capacity from recycled 18650 notebook batteries. Values maybe empty before new battery start.

Temperatura

This channel logs real-time data from a simulated satellite-linked forest fire alert system using MQ2 (smoke), DHT11 (temperature & humidity), and IR sensors. Data is transmitted via ESP8266.
