Model Number: S-SPO2-0004 Brand Name: TAOS Key Specifications/Special Features: DescriptionThe TSL237 light-to-frequency converter combines a silicon photodiode and a current-to-frequency converteron a single monolithic CMOS integrated circuit. Output is a square wave (50% duty cycle) with frequency directly proportional to light intensity (irradiance) on the photodiode. The digital output allows direct interface to microcontroller or other logic circuitry. The device has been temperature compensated for the ultraviolet-to-visible light range of 320 nm to 700 nm and responds over the light range of 320 nm to 1050 nm. The TSL237 is characterized for operation over the temperature range of 40°C to 85°C and is supplied in a3-lead clear plastic side-looker package with an integral lens. When supplied in the lead (Pb) free package, the device is RoHS compliant.ApplicationTSL237 can be used in SpO2 and Pulse measurement, such as Finger Pulse Oximeter， Beauty Products, etc. Shipping Information: FOB Port: Shenzhen
