MODBUS Temperature, humidity and Barometric Pressure Transmitters

Available from Audon Electronics are a range of low cost temperature, humidity and barometric pressure sensors with an RS485 output. These units can communicate via a simple ASCII "Adam 4000 series" compatible protocol or the industry standard MODBUS RTU protocol for use with common SCADA software.

Measured temperature, relative humidity, barometric pressure are converted to serial output with a RS485 interface. Transmitters are available in wall-mount, duct-mount and bar types. Also, types with T+RH probe on a cable are available.

They featuring a large dual line LCD for local display of temperature, humidity, pressure or other calculated value and the microprocessor design ensures maximum long term stability and fail indication.

The transmitter works with ModBus RTU communication protocol or with ADAM compatible ASCII protocol. The protocol is user selectable in special configuration mode by means of the PC.

Economical Ethernet Temperature/Humidity email Alarm

The HWg-STE web thermometer is an Ethernet based two channel alarm unit configured using a built-in web server. The HWg-STE web thermometer is configured using a built-in web server which can also show the current temperature (and humidity). If the temperature (or humidity) exceeds a specified threshold, an e-mail alert is sent. The HWg-STE Thermometer is also fully SNMP compatible. Free windows software HWg-PDMS for datalogging, graphical overview and MS Excel export is included.

The HWg STE represents an effective and economic solutions in the applications like air-conditioning failure, heating system monitoring, cooler/freezer monitoring, heating optimization and food storage.

Digital Event Recorder - Date and Time stamp 4 digital inputs

The S7841 is a 4-channel digital event recorder which can record the date and time when any of it's 4 inputs changes state. The inputs can be volt-free contacts, such as door contacts, machine switches, or it can be a voltage signal. Data can then be downloaded to a PC for storage and analysis. A LCD display shows the current sate of the logger.


The S7841 is a stand-alone device, and the replaceble internal battery typically lasts 4 years. Up to 16254 events can be recordered per input, and spikes of less than 1/2 second are ignored to prevent false results.

Data download is via a Rs232, USB or Ethernet connection.

DLP-IO20 - USB DAQ just got cheaper!

The DLP-IO20 Data-Acquisition Module from Audon Electronics is a low-cost, easy-to-use data-acquisition system for analyzing AC voltages, driving 5-volt relays, controlling and monitoring processes and measuring DC voltages in the range of 0-5 volts. This module provides topside wire terminal blocks for the wiring connections.

The 20 channels on the DLP-IO20 are broken down as follows: 3 outputs with high current relay/LED drivers and 17 digital I/O; 14 of which can be set to analog input mode. The DLP-IO20 also provides two latching relay contacts. Each of the channels and relay contacts can be controlled via simple, multi-byte commands. All operational power is taken from the host PC via the USB port.

The mode of each I/O is automatically changed with each command sent. For example, if an I/O is set to Digital Output-High and then the Digital Input Mode is selected, the I/O is first changed to Input Mode and then the high/low state is read and returned to the host.
