About the Mqtt weather station PCB

Mqtt weather station is an open source PCB design by uw-madison-chem-shops, published on GitHub under the CERN-OHL-P-2.0 license. It is a 2-layer board measuring 91.4 × 66 mm, with 23 components from 17 distinct parts.

Other key parts include the BME280, CD4060BM96 and Adafruit_HUZZAH_ESP8266_breakout. By type, the board carries 9 resistors, 5 capacitors, 2 ICs, 2 transistors, 2 diodes and 1 module.

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

From the project

Simple station for monitoring environmental conditions in the lab over MQTT.

Simple station for monitoring environmental conditions in the lab over MQTT.

Based on the Bosch's BME280 humidity, pressure, and temperature sensor. Using Adafruit's breakout board.

Designed to work with mqtt.chem.wisc.edu.
