Our data loggers supports the MQTT protocol, opening a new IoT world of flexibility. The MQTT protocol implements a publish/subscribe messaging model, making it possible to flexible distribute and share information.
Commands can be send to the serial sensor (RS232/RS485/SDI-12) or accessory (RS232) port on the main PCB as well as on option boards. The (binary) data contained in the MQTT payload will be passed transparently 1 to 1 to the concerned serial device and the response will be replied as (binary) payload 1 to 1 as well, it’s up to the MQTT-client to format and interpret the data to/from the serial device (which could be MODBUS/RTU, SDI-12, NMEA-0183 or any other protocol).
Data logger is designed to operate autonomously and stand-alone at off-grid locations, but often there are requests about the possibility to share readings with a locally present SCADA system.
Because of low-power considerations data logger goes to sleep after performing sensor readings and can therefore not be interrogated by an external system.
The data logger is available with several power provisions e.g. a 3.6 Volt Lithium batteries, 8..28V DC input, 12V solar panel input or integrated solar panel with battery charger.
When equipped with the integrated solar panel a complete self providing remote monitoring station can be arranged, all you need is a logger and applicable sensor(s).
This self providing cellular logger is costs saving, because you don't need: a) solar panels, b) big batteries, c) cellular modem and d) encapsulating cabinet.
