This channel updates information about the DC motor.The values from the temperature sensor,speed sensor and the current sensor are read using Arduino Uno and these values are streamed via thingspeak API to the front-end Freeboard.Simply ,its , Remote Moni

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.

Este canal recopila datos de calidad de aire usando sensores MQ135, MQ2, MQ7 y MH-Z19 para monitorear gases tóxicos, humo/GLP, monóxido de carbono y dióxido de carbono.

IoT project using ESP32 + Arduino Sensor Kit Base. Collects temperature, humidity, air pressure, light, and sound RMS, then uploads to ThingSpeak for cloud visualization.

This channel receives temperature, humidity, and other weather data.

Smart Warehouse project: automated temperature and humidity monitoring and control system using Arduino Nano, DHT sensor, relays, LCD, and ESP8266. Data is logged to the cloud for visualization and alerts.

Water level monitoring.
