Wireless traffic data collection can be achieved on site either by infra-red or by Bluetooth connection using a PDA. The new Eco-combo range of loggers and sensors makes traffic data collection easy and discreet.
The device is easily installed in a conventional manhole or specially-designed unobtrusive Eco urban chamber, and there is no need to open the manhole to collect the data. Data is quickly retrieved from up to 6m away using the Bluetooth connection.
For automatic data transfer via telemetry using GSM modem please refer to the Eco-combo GSM.
