Measuring data from a digital sensor
ESP8266 boards can be used to read and monitor data from both digital and analog sensors. To demonstrate this, we are going to measure data from a digital temperature and humidity sensor then display the data on the serial monitor.
Getting ready
In this tutorial, you will need an ESP8266 board, a USB cable, and a few other components, which include:
- DHT11 temperature/humidity sensor (https://www.sparkfun.com/products/10167)
- 10 kΩ resistor
- Breadboard
- Jumper wires
The DHT11 pin configuration is shown in the following diagram:
First mount the ESP8266 board and the DHT11 sensor onto the breadboard. Connect a 10 kΩ pull up ...
