The DHT11 Sensor Server is a simple application running on an ESP8266 WiFi-capable controller that allows you to retrieve temperature and humidity data from a DHT11 sensor. The DHT11 Sensor Server is ...

Today we will do a similar project and use the Google sheet as IoT cloud to log the data generated by a Temperature Sensor. Here we will use ESP8266 NodeMCU to send the temperature and humidity data ...

Arduino code to implement a MQTT-enabled air quality sensor using an ESP8266 (NodeMCU) microcontroller, BME280 climate sensor, SGP30 gas sensor, and PMA5003I particulate matter sensor. It is designed ...

It has enough digital pins for our application. To know more about this check out ESP8266 NodeMCU projects. Capacitive Soil Moisture Sensor The job of a soil moisture sensor is to detect the water ...

You have an ESP8266 board like the Wemos D1, a Li-Ion battery, you want to build a small battery-powered sensor that wakes up every few minutes to do something, and you don’t want to delve into ...

First the obvious-in-retrospect fail. [Richard] built a board with a temperature sensor and an ESP8266 module to report the temperature to the Interwebs. If you’ve ever put your finger on an ...

ANAVI Thermometer was launched on CrowdSupply in January. It is an ESP8266 WiFi board with a built-in DHT22 temperature and humidity sensor, support for external DS18B20 waterproof temperature sensor, ...
