2024/01 MicroView temp and humidity


I wanted a simple and accurate thermometer and humidity sensor.

The small display shows:






- Sparkfun DEV-12923 - Arduino MicroView - OLED Arduino Module

- one 10k resistor          

- switch or momentary button

- 6-9v battery or wall power upply


Total parts cost: Approximately $50

DHT11 Data Sheet

   A few comments:

1. Very simple circuit and code.

2. Be sure you specify the correct DHT chip.  I had mistakenly used DHT22 and it gave massively weird readings.  Mine was a DHT11.
