Manuals & Software

Weather station controller and datalogger CM‑1TM is an weather station control module included in all Dyacon pre-configured weather stations.

CM‑1 is integrates the sensor interfaces, LCD user interface, logging memory, cell phone (wireless version), lightning detection, solar charge controller, USB device port, Modbus inputs, and Modbus output. CM-1 is compatible with a range of sensors for typical weather station applications.*

CM‑1 is available in two principle variations, cabled and wireless.
The cabled weather station is powered by 12 VDC to 24 VDC. Data is available through the Modbus slave port or data log.
The wireless weather station is a fully autonomous weather station (AWS) and includes solar power module, battery, and embedded cell phone. In addition to the above features in the cabled version, data is also available through SMS, email, ftp, and WeatherUnderground.

Mounting hardware is included for both pole and flat surface.

CM‑1 is a dedicated weather station controller, it does NOT require programming or a costly development environment like many other weather stations based on data loggers. In fact, very little technical knowledge is required. If you can install a light switch or set the time on a microwave oven, you have the skills to setup, configure, and maintain a Dyacon weather station.

Key Features


CM‑1TM is an integrated meteorological station control module housed in a sealed enclosure. Weather information reports are transmitted through SMS text messages or through the Modbus slave port. Aside from the 12 VDC power adapter, no additional data modules, circuit boards, converters, transmitters, or adapters are required.

Sensor Compatibility

CM‑1 was designed to be fully compatible with the following Dyacon sensors:

Digital (Modbus) wind and air sensors

Analog sensors (thermistor, pyranometer, soil moisture)

Rain gauge (0.01″ or 0.2 mm)

Analog Inputs

Two analog channels provide 24‑bit resolution. Analog ports can be used with thermistors, pyranometers, soil moisture sensor, and other analog sensors compatible with a 2.5 V reference.

Modbus Sensors

Power and data are supplied through a 4‑wire connection to the air sensor (TPH‑1) and wind sensor (WSD‑1).

Rain Gauge – Counter Input

CM‑1 is compatible with tipping bucket rain gauges that use a switch interface. The rain gauge input can be configured for 0.01″ and 0.2 mm rain gauges.


To minimize the effects of solar heating on the air sensor, CM‑1 includes an aspiration (fan) output that is compatible with TPH‑1. An upgrade kit is also available.


Machined aluminum brackets are included for pole or surface mounting. The included band clamps can accommodate pipe sizes from 3/4″ to 3″.


Tripod‑1 provides a versatile and secure platform for mounting CM‑1 and the related weather sensors.

A full range of sensors and installation accessories is available for industrial, agricultural, and public service applications. Please review the available sensors on this website; contact Dyacon for additional assistance.
