Termometro wireless via ESP 8566

this is local

Rolling 8.5 minute average/minimum/maximum of wind speed measured in miles per hour using homemade wired anemometer. Homemade Wireless temperature transmitter using MCP9700A.

Using an ESP8266 ESP-01 module and an Arduino Pro Mini 3.3V I wirelessly update all outputs from my thermostat to here for data analysis and because it's cool. This requires a voltage divided rectifier since thermostats run at least 24 VAC RMS.

This sensor uses an ESP8266 Wireless chip directly connected to a DHT22. Its currently being tested for consistency and stability. The intention with this sensor is to be a low power sensor that I can run from a battery (I am planning to use a 18650).

Simulation de données d' une planche standard

Temperature from an array of wireless sensors in a mesh topology based on IEEE 802.11 b/g/n. Using NodeMCU - ESP8266 and Espressif NON-OS SDK with Mesh API's. Each node is in a network level where the first one is the ROOT NODE.

Power Node sensor with bme280, measures temperature, humidity, pressure and battery voltage. Sends measurements to gsm master node every 10 min. Current consumption ~ 10uA at 2.6V.
