1-Wire ambient light sensor TSL200

TSL200 is a 1-Wire ambient light sensor
with 83000 lux working range and IP30 protection.


TSL200 is a 1-Wire ambient light sensor with high dynamic range and resolution. The dynamic range of 83000 lux guaranties precise measurements even directly to the light sources.

The sensor measures the intensity of the visible light. It has a strong infrared (IR) rejection. This makes the spectral response of the sensor very close to the response of the human eye.

The 1-Wire ambient light sensor measures up to 83000 lux. It has automatic full-scale settings. This capability allows light measurement over a 23-bit effective dynamic range. This makes the sensor very precise on dark as well as on a very intensive light.

The internal digital signal processing guarantees the long-term stability and repeatability of the measurements. With full factory calibration, the sensor requires no additional calibration on the customer’s side.

The sensor communicates over the 1-wire interface. In order to make easier daisy-chain wiring, there is two RJ-11 connector available on the panel.

The presence of a unique number for each sensor allows installation of multi-sensor systems. Moreover, the 1-Wire ambient light sensor can be combined with sensors for other environmental parameters to build a single-point multiparameter environmental monitoring.


  • Wide dynamic range (83000 lux) for direct light source measurements;
  • Automatic full-scale setting for better resolution;
  • Measuring the intensity of light as visible by the human eye;
  • IP30 ingress protection;
  • Fully digital operation for excellent long-term stability;
  • Unique 64-bit serial number for identification in multi-sensor systems.


  • Office environmental monitoring;
  • Building’s management systems (BMS);
  • Light sources qualification.

The sensor can be used with

  • Ethernet IO module TCW241
  • GSM-GPRS remote IO module TCG140
