Case for ESP8266 ESP-01 DHT11 module

thingiverse

This is a case for the DHT11 module, available on various sellers via links like [https://www.aliexpress.com/store/product/ESP8266-ESP-01-Serial-Wireless-WIFI-Module-DHT11-Temperature-Humidity-Sensor-Transceiver-Receiver-For-Arduino/1414081_32841909538.html?spm=2114.12010615.8148356.16.1f786a1dJnQdsx](https://www.aliexpress.com/store/product/ESP8266-ESP-01-Serial-Wireless-WIFI-Module-DHT11-Temperature-Humidity-Sensor-Transceiver-Receiver-For-Arduino/1414081_32841909538.html?spm=2114.12010615.8148356.16.1f786a1dJnQdsx) that combines the module with the ESP-01. I've noticed a common issue with these devices: temperature readings are often skewed high due to heat from the ESP8266. To fix this, I recommend bending the sensor so it's no longer affected by the heat. Power is provided by a micro-USB breakout available at the same sellers as the module. You can find one at [https://www.aliexpress.com/store/product/10Pcs-Lot-MICRO-USB-to-DIP-Adapter-5Pin-2-54mmDip-Female-Connector-Micro-Usb-Type-PCB/1414081_32672630815.html?spm=2114.12010615.8148356.1.75e26b68HcDhXb](https://www.aliexpress.com/store/product/10Pcs-Lot-MICRO-USB-to-DIP-Adapter-5Pin-2-54mmDip-Female-Connector-Micro-Usb-Type-PCB/1414081_32672630815.html?spm=2114.12010615.8148356.1.75e26b68HcDhXb). For software, I'm using esphomeyaml on the device to log values to Home Assistant. Update 2019-03-23: The design has been adjusted to be slightly larger to allow bending the sensor out and avoid skewed readings caused by the ESP8266's heat.
