Good value for electronic experiments
Solid build quality for the price. It handles the 0-40KPa range well. I deducted one star because the documentation could be more detailed regarding calibration.

Excellent sensitivity
I was surprised by how sensitive this little module is. It detects even small changes in liquid level. Great addition to my sensor kit.

Perfect for my aquarium project
This sensor works flawlessly for monitoring water levels in my custom aquarium setup. The readings are stable and the analog output is easy to read with an Arduino.
Q: Does this come with a library for Arduino?
A: While we do not provide a proprietary library, this sensor uses standard analog output which works with basic Arduino code. Many community libraries for pressure sensors are compatible with its signal type.
Q: Is this module waterproof?
A: The sensor element is designed to measure liquid pressure, but the PCB itself is not fully waterproof. We recommend coating the electronics or placing them in a waterproof enclosure while exposing only the pressure port to the liquid.
Q: Can it measure negative pressure or vacuum?
A: No, this specific model is designed for a gauge pressure range of 0 to 40 KPa. It cannot measure negative pressure or vacuum conditions.
Q: Can this sensor be used directly with a Raspberry Pi?
A: Yes, it can be connected to a Raspberry Pi via the GPIO pins using an ADC converter if you need digital readings, or directly if your Pi model supports analog input via an add-on board.
Q: What is the maximum temperature this sensor can withstand?
A: The operating temperature range is -20°C to 85°C. Exceeding 85°C may damage the sensor or affect accuracy.
