Fast Shipping
Arrived quickly and was well packaged in anti-static foam. No damage to the pins. Ready to solder or use with headers.

Reliable Sensor
Been using this for a month in a smart lighting project. It hasn't drifted and responds quickly to changes in ambient light.

Precise Measurements
I compared the readings against a professional lux meter and it was surprisingly close for the price. Great for home automation projects.

Good Value
The module works well but note that you might need external pull-up resistors on the I2C lines depending on your microcontroller.

Works Great with Arduino
This sensor module is very easy to integrate. I used it with an Uno and the standard library worked immediately. Readings seem consistent.
Q: What is the maximum cable length for I2C connection?
A: For reliable communication, keep the I2C cables under 30cm. Longer distances may require signal boosters.
Q: Can I use this with 5V logic levels?
A: Yes, the module supports operating voltages from 3.3V to 5V DC, making it compatible with most 5V microcontrollers.
Q: What is the default I2C address?
A: The default I2C address is typically 0x23, though some variants may use 0x5C depending on the ADDR pin configuration.
Q: Is this sensor waterproof for outdoor use?
A: No, the module is not waterproof. You must place it inside a weatherproof enclosure if using it outdoors.
Q: Which library do you recommend for ESP32?
A: There are several available in the Arduino IDE library manager. Searching for 'BH1750' will yield compatible libraries.
