TSR4S
SIGFOX Wireless Radon Probe TSR4S
- On-line monitoring of measured results on WEB (radon concentration, temperature, humidity)
- Alarms over SMS, email, call if radon cross the limit
- Internal memory for backup of measured results (downloading over USB)
- Monitoring of GPS position on map
- Accumulator life up to 1 year after full charging or using permanent power adapter 230V
- User friendly web application, graphs, data export
- Unique web access for management of probes
Portable radon measuring probe with rechargeable accumulator allows to watch radon results remotely over wireless mobile network of Internet of Things (IoT) SIGFOX. The probe can be placed anywhere in the world where this mobile network has coverage. The probe autonomously sends in regular intervals measured result over wireless network SIGFOX to web server where is possible to view and download results via internet and internet browser in web application TESLA – MONTES. Coupled with delivery is charged wireless connectivity and web application regular service fee. Configuration of probe and setting regular interval of sending are made over USB port and application in PC. Probe includes GPS module for better localization in wider measurement networks. It is similar like TSR4 probe only with another type of wireless communication SIGFOX. In case of need the TSR4S can be change to TSR4 or TSR4M and back by easy and quick way in product factory.
Probe is designed for continuous measuring of radon concentration. Portable probe basis is a measuring chamber with a semiconductor photodetector. Radon enters the chamber by diffusion through the input filter on the bottom of probe. The probe measures in autonomous and time continuous way. It processes results every 2-minute intervals and from this counts radon concentration (1 hour moving average – average of 30 2-minute process intervals). The probe sends results to server and saves time records in its internal memory (typically at an interval of 1 hour). Next saved value to internal mamory is time record of measuring energy spectrum (typically at an interval of 12 hours). The probe can be switched on/off by switch. LEDs „STAT“ a „CHRG“ indicate current status of probe.
