Compact and reliable
Small form factor fits perfectly into my custom 3D printed enclosure. Only giving 4 stars because the pin headers were not pre-soldered, but that's expected for DIY modules.

Perfect for my smart home project
This module works flawlessly with Home Assistant. The SHT40 sensor provides very accurate readings, and the Bluetooth range is impressive for such a small device.

Accurate humidity tracking
Using this to monitor my indoor garden. The humidity response time is fast, and the low power consumption means my coin cell battery lasts for months.

Excellent for learning IoT
Bought this for a university project. It connects easily to my phone via nRF Connect app. The 3-axis accelerometer data is smooth and easy to parse.

Great hardware, documentation could be better
The nRF52810 chip is powerful and the accelerometer is a nice bonus. I had to dig into the Nordic SDK docs to get the BLE advertising working exactly how I wanted, but once set up, it's solid.

Best value BLE sensor module
I've tried several similar modules, and this one offers the best balance of price, performance, and power efficiency. The temperature accuracy is within 0.2 degrees.
Q: Is the firmware pre-flashed or do I need to program it myself?
A: The module comes with a basic demo firmware to test functionality immediately. However, for custom applications, you will need to flash your own firmware using a J-Link or similar SWD programmer.
Q: Is this compatible with Arduino IDE?
A: Yes, this module is compatible with the Arduino IDE when using the nRF52 core by Sandeep Mistry or the official Nordic Semiconductor nRF52 Arduino core.
Q: Does this module come with a battery included?
A: No, the module does not include a battery. It is designed to be powered by an external coin cell (CR2032) or a LiPo battery connected via the designated pins.
Q: What is the operating temperature range of the SHT40 sensor on this board?
A: The SHT40 sensor itself operates accurately between -40°C and +125°C. However, please ensure the surrounding electronics and battery used are rated for your specific environmental conditions.
Q: Can I read the accelerometer data via Bluetooth without writing custom code?
A: The default demo firmware primarily broadcasts temperature and humidity. To access accelerometer data over BLE, you will need to modify the firmware to expose those characteristics.
