ESP8266-01 & DHT11 Wireless Temperature Sensor

ESP8266-01 & DHT11 Wireless Temperature Sensor BOM and circuit diagram as PDF under Downloads For flashing the ESP01 modules, or which one to use with the Arduino IDE, you can find plenty of information online. The program to use is also up for grabs. I was primarily concerned with casing and electrical setup. I've posted pictures of the finished sensor. I appreciate your comments, opinions, or suggestions for improvement. Update: ---------- I've now published pictures of the completed device. For electronics connections, I used pre-assembled Dupont cables. I reused a battery from an old laptop battery. All components were secured with hot glue. The screws for the lid are M3. Conclusion and future plans: --------------------------------------- A simple and affordable device for measuring temperature and humidity. In choosing the housing color, I opted for light that shines through the LEDs. This can be distracting in certain situations. My device isn't yet optimized to conserve energy. I plan to remove the LED on the DHT11 module. Furthermore, a bridge for the deep-sleep function on the ESP8266 module will be retrofitted in the future. This should enable the whole device to provide data for an extended period without constant charging. The values provided by the DHT11 module are quite inaccurate. I plan to replace this sensor with the DHT22. If necessary, I'll design a completely new board that carries this sensor, has a slot for the ESP8266, and powers the whole system. This will likely become a separate project that I'll publish here when it's time. Until then, have fun building! I'd appreciate your feedback.
