The 230-WS-32BP Barometric Pressure Sensor offers impressive stability in a small package at an affordable price.
Product Details
The 230-WS-32BP Barometric Pressure Sensor offers impressive stability in a small package at an affordable price. The sensor has less than 1.5% error over a pressure range of 15 to 115 kPa (4.43 to 33.96 Hg). It operates on less than 50 mW and has a voltage output of 0 to 5 Vdc, which is linearly proportional to barometric pressure.
