OPT101 Illumination Sensor Light Intensity Sensor Module

The OPT101 is an illuminance photosensor that integrates a photodiode and a specially optimized op-amp. The transparent package allows the photodiode to have a larger sensing surface with higher sensitivity and a wide spectral response range (infrared to visible light 300nm-1000nm).

Parameter:

Working voltage: 2.7 ~ 36V
Working temperature: 0°C~70°C
Photodiode light irradiation area: 5.2mm2
Photocurrent: 0.45A/W (λ = 650nm)
Output voltage ratio: 0.45V/uW
Analog voltage output range: Vs-1.15
Bandwidth: 14KHz
Static power consumption: 120uA

PIN Description:

VCC: power supply positive pin
-V: negative supply
-IN: the inverting input of the internal op amp and the negative of the internal photodiode,
Do not connect or apply feedback that is abandoned in the operation
1M: Internal 1MΩ feedback resistor input
OUT: Amplifier output
COM: Internal photodiode positive, generally connected to GND
Note: The module does not solder the CEXT external capacitor and the REXT external resistor, leaving the pad for easy extension.
