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.

THINGSPEAK_TEST

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

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

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.
