Monitoring of temperature, humidity and status of digital inputs

Hero Web Sensor

Hero Sensor Web is a small module that allows to monitor data from up to 4 different sensors. It is adapted to read data from temperature, humidity, etc. sensors and 2 digital inputs. The device is equipped with a readable 7-segment LED display in red, on which are available, among others measured values, current IP address and DHCP service status.

Communication

Communication with the module is done via a LAN. The user can read the measured data via:

  • embedded web server, using a standard web browser (preferred browsers are MOZILLA FIREFOX, OPERA, CHROME);

  • Windows / Linux command line

  • HTTP protocol

  • MQTT protocol

  • SNMP protocol

  • MODBUS TCP protocol

  • e-mail messages

  • syslog commands

Application

The device’s main page displays the current readings from the sensors and the status of the digital outputs.

Sensors support

Hero Sensor Web allows to set the warning and alarm parameters measured above which alerts are activated. The warning status is signaled by the yellow reading illumination of the given channel, alarm state by red. The data read from the sensors can be sequentially presented on the LED display. In addition to the upper and lower warning and alarm thresholds, the name and address can be set separately for each sensor,  also hysteresis, correction of indications, define whether data should be saved in the device’s memory, specify how often the device should send information messages.

The module can be programmed by the user to respond to exceeding the set thresholds or to transfer the current value taken from the sensors by sending an e-mail, sending a TRAP message, sending a TCP frame, sending a message to the MQTT broker, sending a message to the Syslog server. Data from the module can also be read and written using the Modbus TCP protocol.

The module supports SNTP protocol, so it gets the current time from SNTP servers. Synchronization occurs every 10 minutes.Time is used to log data from sensors in the internal memory. The data is available in the form of a time function on a graph or csv file.

Digital outputs

Hero Web Sensor has two output channels: relay – OUT1 and transistor OC – OUT2. Each of the outputs can work in the following modes: Astable – the relay cyclically shortcuts and opens the contacts, Bistable – the relay has a fixed position, is on or off, or the mode of single triggering – TimeBase.
