Thermo anemometer
About the Thermo anemometer PCB
Thermo anemometer is an open source PCB design by zhangyuyi99, published on GitHub. It is a 2-layer board measuring 60 × 50 mm, with 26 components from 23 distinct parts.
Other key parts include the LM358, LM317_TO-220 and AZ1117-5.0. By type, the board carries 7 connectors, 6 resistors, 5 capacitors, 4 jumpers and 3 ICs.
From the project
A hot wire anemometer based on ESP32
This project includes the design and implementation of a Wi-Fi enabled anemometer. The anemometer consists of a hardware portion which includes the PCB designs for the main board and logic board and a software portion which includes the firmware for operating the anemometer. The anemometer uses a hot wire method for wind speed measurement, and it includes a function to monitor battery voltage, disabling wind readings when the voltage drops below 7V until it recovers.
