About the TemperatureDisplay PCB

TemperatureDisplay is an open source PCB design by RobThree, published on GitHub under the MIT license. It is a 2-layer board measuring 25.7 × 34.4 mm, with 4 components from 3 distinct parts.

It belongs with the displays & leds, sensors and iot & wireless designs in this gallery.

From the project

Measures temperature and humidity using a GXHT30 and displays this information on an SSD1306 OLED display. Offers a HTTP endpoint to read values as JSON, also outputs values on serial.

Uses an Wemos D1 mini with a GXHT30 I²C temperature & humidity sensor and a SSD1306 I²C 0.96" OLED display.

This project supports OTA updates, uses the WiFi manager to configure the WiFi and provides a REST API to get the temperature and humidity as JSON. The readings (and display) are updated every 2 seconds (by default, configurable) and also output to serial.
