Accurate humidity sensing

Using this to monitor my indoor garden. The humidity readings help me automate my misting system effectively. It took a few minutes to stabilize upon first power-up, but works great since then.

Compact and robust

The form factor is perfect for fitting into tight spaces on our robot chassis. It withstands vibration well and provides consistent data over I2C. Will definitely order more for our next batch.

Reliable industrial grade performance

We deployed ten of these in our warehouse monitoring system. They have been running continuously for three months without drift or failure. The TTL serial output makes it easy to interface with our existing PLCs.

Good value, clear documentation

Solid build quality and the pinout is clearly labeled. I appreciated the included library examples which made integration quick. Only giving 4 stars because the soldering pads are a bit small for beginners.

Perfect for my weather station project

This module works flawlessly with my Arduino setup. The pressure readings are very stable, and the humidity data from the BME280 variant is accurate compared to my reference meter. Highly recommended for DIY enthusiasts.

Great for learning embedded systems

Bought this for my university thesis on environmental monitoring. The sensor responds quickly to changes in temperature and pressure. The price point is unbeatable for the features provided.

5 FAQ

Q: Do you provide sample code for Raspberry Pi?

A: Yes, we host Python libraries and example scripts for Raspberry Pi on our GitHub repository, linked in the product manual PDF available in the download section.

Q: What is the difference between the BME280 and BMP280 versions?

A: The BME280 measures temperature, pressure, and humidity. The BMP280 measures only temperature and pressure. Please select the correct variant based on your humidity sensing needs.

Q: Is the enclosure waterproof?

A: No, the PCB itself is not waterproof. For outdoor use, we recommend placing the module inside a breathable weatherproof enclosure to protect it from direct rain while allowing air flow.

Q: Does this module work with 5V Arduino boards directly?

A: Yes, the module includes a voltage regulator and level shifting, making it safe to use with both 3.3V and 5V microcontrollers like the Arduino Uno.

Q: Can I daisy-chain multiple sensors on the same I2C bus?

A: Standard modules usually have a fixed I2C address. To use multiple sensors, you may need to modify the address pin (if available on your specific revision) or use an I2C multiplexer.
