RSA-STLA Ambient Light Sensor / Transmitter
Applications & Features
- RSA-STLA series are designed for detecting ambient light level. They can be widely used for lighting control applications in various indoor or outdoor environments such as warehouse, computer room, workshop, record room, library, school, shopping mall, smart home, hotel, park, airport and railway station, etc.
- High sensitive sensor and precise linear amplifier circuit, accurate measurement and temperature compensation, good long term stability and reliability
- Light and state of art housing supplies two different install
and wiring ways, with high protect rate, delicate structure
- Power and output have over voltage and reverse polarity
protection, high reliability and anti-interference capability

Models
- Illumination is the unit of light intensity, popular defined as flux (Lm) on unit area(m2), also known as lux.
- Generally, in summer’s sunny day the illumination will be 30~300,000 lux; cloudy day is 3~10,000 lux; sun rise/sun set is 300~400 lux. Illumination for indoor is 10~2000 lux for different lighting status and <1 lux during night without any lighting
