Wind Speed Anemometer NPN Output - Arduino Compatible
- Brands China Code: SN-WIND-NPN
Weather is one of the most important factors for human and life and food security, and wind speed is one of the elements to measure in weather stations.
This is a wind speed detector or a.k.a anemometer. It is portable, easy to carry and assembly, made of polycarbon which is anti-corrosion rust at the same time to overcome the ABS plastic aging problems. The bottom outlet and the outlet side of the equipment are compatible with each other. The output signal pulse (NPN/Open-drain output) is widely used in wind speed measurement in greenhouses, environmental protection, weather stations, ships, docks, and breeding environments.
This is an example schematic diagram for the connection between NPN Anemometer and Arduino. This connection requires a pull-up resistor to logic voltage, recommended to use a 5.1k Ohm resistor.
The below shows the size image for 5V Wind Speed Anemometer NPN Output:
Here is a sample code to test the speed when the power connected to 5-12V.
