Mouser Electronics Stocking the ams TSL2740 Light and Prox Sensor

June 13, 2019 Alix Paultre

Mouser Electronics is now stocking the TSL2740 combined ambient light and proximity sensor from ams. Offering very high sensitivity at millilux-level intensity, the TSL2740 combines an ambient light sensor and a proximity light-to-digital sensor that approximates the human eye response to light intensity under varying lighting conditions. Offering a wide dynamic range, the 2.0 mm × 2.0 mm × 0.5 mm device transforms light intensity to a digital signal output through a 1.8V I2C interface.

Measuring reflected IR light emitted from an external LED, the proximity engine features automatic ambient light subtraction, as well as offset adjustment registers to compensate for unwanted IR energy reflection at the sensor at a range of up to 10 cm. The device’s ALS sensor features both visible and IR output channels. The visible channel has a photodiode with a photopic interferometric UV- and IR-blocking filter. The IR channel has a photodiode with an IR pass filter. Each channel has a dedicated integrating data converter which converts photodiode current into a 16-bit digital output that can be interfaced with a microprocessor.
