WIFI wireless temperature and humidity sensing node

Overview

Temperature and humidity sensing node based on ESP8266

Low power consumption, one-cell design dry battery power supply
DCDC rushes to the 3.6V ( QX2304L36E ) voltage range
DHT11 sensor, MOS controlled power supply to prevent unnecessary power consumption
Using CH340C to UART and supporting the corresponding circuit, the firmware can be directly burned, eliminating the need for a crystal oscillator and reducing the occupied space.
USB power supply uses LDO to step down to 3.3V
Tentatively, I plan to use the NODEMCU platform to write LUA. If low power consumption is not enough, I will consider using the ARDUINO platform. If it still doesn't work, I will use the ESP IDE. (Yes, the program is not implemented yet.
