Description

TESLA Radon Sensor "TSRS (UART)" and "TSRS2 (RS485 - MODBUS)"

Intelligent detectors of radon concentration with simple serial interfaces UART, RS485 - MODBUS and RELAY for easy implemention into third party system. Suitable for integration into smart buildings, industrial systems and systems of air quality. Connection of probe is always by 4 - wires, 2 wires are for serial half-duplex data or for relay and 2 wires for DC powering. Coupled with sensors are delivered descriptions of interfaces and protocols for easy development and implementation of processor program. Current values of radon concentration, temperature and humidity are possible to read from sensors and also set limit for switching of alarm relay. Also is possible to download time records of radon concentration and energy spectrum from sensor internal memory.

Radon Sensor TSRS

TSRS sensor has alarm RELAY and wired serial interface UART. RELAY is design for remote alarm signalization of crossing radon limit over 4-wires cable (severel 100 meters). UART interface is design for direct connection with processor unit for short distance (severel meters) over 4 –wires cable too. Powering from +5VDC to +12VDC.

Radon Sensor TSRS2

TSRS2 sensor with wired serial interface RS485 is design for bus connection of more sensors with processor unit for long distance (severel 100 meters). Powering is in range +7VDC to +15VDC. Communication type and rate is possible to set by external switches as well as bus address of device.
