1246

The 1246 is a Flora Lux Sensor for use in a wide range of light situations. Compared to low cost CdS cells, this sensor is more precise, allowing for exact lux calculations and can be configured for different gain/timing ranges to detect light ranges from up to 0.1 to 40000+ Lux on the fly. The best part of this sensor is that it contains both infrared and full spectrum diodes, that means you can separately measure infrared, full-spectrum or human-visible light. Most sensors can only detect one or the other, which does not accurately represent what human eyes see (since we cannot perceive the IR light that is detected by most photo diodes). The sensor has a digital (I²C) interface. Attaching it to the flora is simple - line up the sensor so its adjacent to the SDA/SCL pins and sew conductive thread from the 3V, SDA, SCL and GND pins. They line up perfectly so you will not have any crossed lines.

• Approximates human eye response
• Precisely measures illuminance in diverse lighting conditions
• Board/chip uses I²C 7-bit addresses 0x39, 0x29, 0x49, selectable with jumpers
• -30 to 80°C Temperature range
