MS-135 Description


Dyacon MS‑135™ is a WiFi weather station that includes basic instruments and solar power for a fully autonomous solution. MS-135 is best when used near existing network infrastructure.


MS‑135™ includes a control module, wind sensor, temperature-pressure-humidity sensor, solar power module, and mounting hardware. Other sensors such as rain gauge, solar sensor, and soil moisture sensor may be added.


MS‑135™ can be used in both wired and wireless applications. The embedded WiFi module uploads to DyaconLive or Weather Underground. The weather station controller includes a Modbus RTU cable connection to automation controllers or computers.


MS‑135™ can be located for optimal measurements, whether in the backyard, at a summer cabin, around evaporation ponds, or other locations where your 2.5 GHz WiFi network is accessible.
Add Tripod-1 for permanent or portable installations.

Key Features

Basic Configuration

MS‑135™ is shipped with a control module, wind sensor (WSD‑1), air sensor (TPH‑1), solar module, mounting brackets, air sensor pipe, and wires. The tripod and aspiration kit are optional add-ons and are purchased separately.

The MS-135 Weather Station uses Dyacon sensors to build a solution that is unique, expandable, and flexible.

Brackets and hardware are included for mounting the components onto 3/4” to 2” pipe or a flat surface. (Tripod is 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 WiFi to upload to DyaconLive, a Dyacon weather station web portal. Data can also be sent to your server. Contact Dyacon for more information.

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 10 W solar module powers MS‑135 and charges an internal battery. The system is designed to go five days of normal operation without solar input. An adaptive power algorithm extends critical operation for several more days.


The MS-135 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‑135 includes a 12 V output for the Smart-Fan aspirated air sensor, which improves the temperature accuracy in sunny conditions.
