Don't overpay for overhitting.
SMART SENSOR
This sensor allows you to keep track of the state of the house (like temperature) more precisely. With this data, you can control your environment better and accurate.
Requirenments
  • 1
    High Accuracy
    For measuring temperature, the accuracy should be around 0.5 degrees.
  • 2
    Simple to use
    The interface, even on the web, should be pretty simple and clear. The logic might be predictable for any customers.
  • 3
    Frequently updated
    Update information as frequent as possible (don't wait a few hours to measure temperature).

v0.3 - PCB design + ESP-12F
One step to forward to making a real product. It's still a prototype, but it's based on ESP-12F (same ESP8266, but more pins and thinner).

Specs:
- 2 x AA batteries
- HX4002B chip
- AHT21 chip
