MS-140 Description


Dyacon MS‑140™ builds on the MS-130 configuration, adding is a solar sensor to the wind and temperature-pressure-humidity sensors. This configuration is ideal for agricultural application and provides the needed input for DyaconLive grower reports with evapotranspiration. The embedded cell phone allows the weather station to be located in remote areas.


MS‑140™ can be expanded with a single-point soil moisture sensor or a multi-depth soil moisture and temperature probe. Leaf wetness sensor and a rain gauge can also be added.
An aspirated radiation shield should be a consideration whenever accurate temperatures are needed.


MS‑140™ uploads directly to DyaconLive and Weather Underground. Email alerts can be set on DyaconLive for temperature, high wind, humidity, and other conditions.
Like all Dyacon weather stations with cell phone, text message weather reports can be sent directly the user’s cell phone, no special software or apps are required.
The Modbus RTU connection can be connected to a local personal computer for viewing data on one of several applications.


MS‑140™ is designed to be easily set up right out of the box; adding the optional Dyacon Tripod‑1 is particularly helpful for portable and permanent installations. Dyacon weather stations do not require any programing or specialized skills to install, configure, or maintain.

Key Features

Basic Configuration

MS‑140™ is shipped with the control module, wind sensor (WSD‑1), air sensor (TPH‑1), solar power module, soil moisture sensor, and tripod with mounting hardware.

This wireless weather station includes an integrated cell phone for SMS weather reports and data uploads to DyaconLive(TM) real-time web portal. It is also compatible with Weather Underground.


The MS-140 Weather Station uses Dyacon modules in building a solution that is unique, expandable, and flexible.

Brackets and hardware are included for mounting the components on 3/4” to 2” pipe. (Tripod sold separately.)

Separate wind and air sensors allow for instruments to be positioned at conventional elevations or as required by the application.


The included Dyacon control module utilizes a cellular module for command and control as well as for weather reports.

Barometric Pressure

A 24-bit ADC digital pressure sensor has the capability of delivering 10 cm (+/- 1.5 mbar) resolution. Barometric pressure is contained in the TPH‑1 sensor.

Wired Data

The control module is equipped with both USB device and Modbus slave ports for connecting to data hosting equipment, such as PCs or programmable logic controllers (PLCs).

Solar Power

A 12 W solar module powers the MS‑140 and charges an internal battery. The system is designed to have five days of normal operation without solar input. An adaptive power algorithm extends critical operation for several more days.


The MS-140 Weather Station is designed to be installed and maintained by the user. Sensors shipped with the unit are preconfigured and tested prior to shipment. Full instructions are provided so that setup can be done by the user without technical support.


MS‑140 includes a 12 V output for the Smart-Fan aspirated air sensor, which improves the temperature accuracy in sunny conditions.
