Compact and precise

Fits easily into my custom enclosure. The size is perfect for tight spaces where larger sensors wouldn't fit. Highly recommend for DIY projects.

Great for kennel monitoring

Works perfectly with my Arduino setup to monitor the humidity in our dog kennels. The serial output is easy to parse and the readings are consistent.

Accurate readings

Good sensor overall. The wiring instructions could be clearer for beginners, but once connected, the temperature data is very reliable.

5 FAQ

Q: Does this work with Raspberry Pi?

A: Yes, this module is compatible with Raspberry Pi via the UART GPIO pins. Please ensure you configure the serial interface correctly in your OS settings.

Q: What is the default baud rate?

A: The default baud rate is 9600 bps. This can be adjusted via command if your project requires a different communication speed.

Q: Can it log data internally?

A: No, this module outputs real-time data only. You will need a microcontroller or computer connected to record and log the sensor readings.

Q: Is it safe for animal enclosures?

A: Yes, it operates on low voltage and generates minimal heat, making it safe for use in veterinary clinics and animal housing environments.

Q: Is the PCB waterproof?

A: The sensor chip itself is resistant to humidity, but the PCB is not waterproof. We recommend housing it in a protective enclosure for wet environments.
