Perfect for robotics projects
This sensor module works flawlessly with my Arduino setup. The serial output is clean and easy to parse. Tilt detection is very responsive and accurate for balancing robots.

Reliable for prototyping
Used this in a prototype for level monitoring. It performed consistently over a 48-hour stress test. Would prefer a surface mount version for final production.

Good value, clear documentation
Solid performance for the price. The datasheet was helpful in getting the baud rate configured correctly. Only minor issue was the pin headers needed a little extra solder.

Great for learning embedded systems
Easy to interface with Raspberry Pi. The inclination detection helped me understand how accelerometer data converts to angles. Highly recommend for students.

Stable readings
I used this for a custom gimbal stabilizer. The noise filtering seems built-in well, providing stable angle data even with slight motor vibrations.

Fast shipping and works as described
Arrived quickly and was well packaged. Plugged it in, sent the command string, and got immediate tilt data. No calibration headaches.
Q: Can this sensor measure vibration frequency?
A: While it is an accelerometer, this module is optimized for tilt and inclination angle detection. For high-frequency vibration analysis, a specialized vibration sensor might be more appropriate.
Q: What is the default baud rate for the serial output?
A: The default baud rate is typically 9600 bps, but it can be configured to other standard rates like 115200 via specific command strings detailed in the user manual.
Q: What is the power consumption in milliamps?
A: The typical operating current is approximately 15mA at 3.3V. It is suitable for battery-powered applications with reasonable capacity.
Q: Is a library available for ESP32?
A: We do not provide an official library, but the serial protocol is simple ASCII text. Many users have written custom parsers for ESP32 which are available on open-source repositories.
Q: Does this module support I2C communication?
A: No, the SC7A20H specifically outputs data via UART Serial. Please ensure your microcontroller has a compatible hardware or software serial port.
