TECNOIOT 1PCS Analog Light Sensor Module ALS PT19 High Dynamic Range Breakout

【ALS-PT19】ALS-PT19 Analog Light Sensor Module High Dynamic Range Light Sensor Breakout Board. Wide detection range: This product is used to detect the photodiode UV light range of 240-370nm, which covers most of the UVB and UVA spectrum. 【UV Sensor】This product has a true UV sensor instead of a calibrated light sensor, so it can convert voltage to UV index by dividing the output voltage by 0.1V. However, the UV LED of this product It is 400 nm. Do not use it if you are out of range of this sensor. 【Signal Amplification】The signal level of the photodiode is very small and is in the nanoampere level, so this product amplifies the operational amplifier to amplify the signal to a more manageable voltage level. Due to the high rejection rate of infrared radiation, the spectral sensitivity of the ambient light sensor approaches the spectral sensitivity of the human eye. 【Less Power Consumption】This product only needs +2.5V-5.5V power supply to supply power. When the sensor detects more light, the voltage will increase. This sensor is much simpler than our Si1145 divider because it only does one thing and provides analog voltage output without the need for a complex I2C setup. This makes it best for simple projects. 【Simple Operation】This product is easy to operate, it only does one thing and provides analog voltage output without complicated I2C configuration program.
