Los Angeles WeatherStation

Basic original components:
Central computer: STC8H1K08
Sensor: BMP280, AHT20
Radio transceiver: Si24R1
Power management: DW06D lithium battery discharge protection chip, SGM2028-3.3 linear voltage regulator
Working principle:
STC8H1K08 reads and interprets environmental information from the sensor, and then passes it through Si24R1 transmission
features:
1. Built-in complete lithium battery discharge protection circuit
2. Fully calibrated temperature, humidity, and air pressure sensors
3. Completely interruptible event processing system, allowing background programs to occupy the CPU core for a long time
4. Fully hardware controlled Data transmission bus
5. Programmable intermittent working mode optimized for low power consumption
6. Built-in filter for air pressure sensor
7. Radio transmission with CRC check
8. Return data with battery voltage
9. Continuous measurement up to 10Hz
10. The small-volume and low-cost
test chart is as follows, a simple test. Blow into the air and observe a rapid rise in humidity and temperature readings, while the air pressure readings remain essentially unchanged.
