Excellent small form factor
Compact size makes it easy to fit into tight enclosures. The 3.3V compatibility is a huge plus for low-power IoT devices. Will buy again.

Good value, needs calibration
The build quality is solid for the price. I did have to calibrate it slightly against a reference gauge to get precise readings, but once set up, it performs consistently.

Reliable for industrial prototyping
We used several of these modules for a prototype fluid monitoring system. They handled the 0-100kPa range perfectly without drifting over a 48-hour test run.

Perfect for my aquarium project
This sensor works flawlessly for monitoring water levels in my custom aquarium setup. The analog output is stable and easy to read with an Arduino Uno. Highly recommended for hobbyists.

Easy to integrate
Plug and play with my ESP32. The documentation provided by the seller was clear, and I had it reading pressure data within minutes. Great for weather station projects too.

Works well but sensitive to noise
The sensor itself is accurate, but I noticed some noise in the readings when placed near a motor. Adding a simple capacitor filter solved the issue, but worth noting.
Q: What is the maximum current consumption?
A: The module typically consumes less than 5mA during operation, making it suitable for battery-powered applications.
Q: Can this sensor be submerged directly in water?
A: No, the electronic components on the PCB are not waterproof. You must connect the sensor to a sealed tube or diaphragm that transfers the liquid pressure to the sensor without direct contact.
Q: Is there a digital output version available?
A: This specific module provides an analog voltage output. However, you can easily connect it to any microcontroller with an ADC pin to convert the reading to digital data.
Q: Does this come with a library for Arduino?
A: Since it outputs a simple analog voltage, no specific library is required. You just use the standard analogRead() function. We provide sample code in the product description.
Q: Which pressure range should I choose for a 1-meter water tank?
A: For a 1-meter water column, the pressure is approximately 9.8 kPa. The 0-40kPa model would provide the highest resolution and accuracy for this specific application.
