Adafruit LPS35HW Water Resistant Pressure Sensor
We have ✅ 4 available of the AF-4258 in our Sydney warehouse. An extra 100 units available with a short lead time.
The Adafruit LPS35HW is a water-resistant barometric pressure and temperature sensor from ST. The sensing element is housed in a ceramic package with waterproof gel protection, making it safe to use in damp and humid environments like outdoor weather stations.
With 24-bit pressure data and 16-bit temperature readings, the LPS35HW delivers ±0.1% hPa accuracy across a 260–1260 hPa range. Unlike the ported LPS33HW variant, this non-ported model is designed for general wet-environment use. It can withstand up to 20× its measurement range and features adjustable data rates with a built-in low-pass filter for clean readings.
