Remote rainfall data for farms, municipalities and sites
|
ES Canada is introducing the WatchDog 4105 Wireless Cellular Rain Station, a compact and affordable rain monitoring station designed for field-based and site-specific rainfall data collection. This mini station is part of the WatchDog 4000 Series, with additional models currently under development. For growers, farm managers, municipalities, utilities and site operators, accurate rainfall information is not only a weather metric. It supports operational decisions related to field trafficability, soil compaction risk, runoff, flood risk assessment and pumping station management. |

Cellular rain monitoring
The WatchDog 4105 records and transmits rainfall data using LTE-M or NB-IoT cellular communication.
Field-based data
Site-specific rainfall information helps support decisions before tillage, spraying or other field operations.
Municipal applications
Rainfall data can support runoff monitoring, flood risk assessment and pumping station management.
Solar powered
The station includes an integrated solar panel and a rechargeable Li-ion battery for remote deployment.
Remote access
Rainfall data is transmitted to SpecConnect and can be viewed through the WatchDog Mobile App.
Rain alerts
Rain alerts can be sent by text, email or phone call to help teams react to changing conditions.
Compact rainfall monitoring for remote sites
The WatchDog 4105 Wireless Cellular Rain Station is designed to collect rainfall data from specific locations without requiring a full weather station installation. This makes it relevant for distributed agricultural fields, municipal infrastructure, golf courses, sports fields and other sites where rainfall can vary significantly over short distances.
The station uses an 8-inch diameter rain collector that meets National Weather Service specifications. The collector is described as freeze-proof and designed for long-term, trouble-free service. The unit includes U-bolts for mounting on a 1.25-inch pole.
Supporting field decisions in agriculture
In agriculture, rainfall data directly affects operational planning. After a rain event, knowing which fields received precipitation can help growers and farm managers assess whether a field may be at risk of compaction before tillage, traffic or other field activities.
- Field-based rainfall tracking for more localized information than regional weather data.
- Improved scheduling of field and job-site activities based on recent rainfall.
- Crop and soil management support where rainfall data contributes to agronomic decision-making.
Rainfall data for municipalities and infrastructure teams
For municipalities, rainfall is a key parameter for stormwater and infrastructure management. The WatchDog 4105 is positioned for applications where real-time, site-specific data can support monitoring of runoff, flooding risk and pumping station operation.
- Stormwater monitoring using local rainfall measurements.
- Flood risk awareness based on rain events at monitored sites.
- Pumping station management where rainfall data supports operational context.
Cellular communication and mobile access
The WatchDog 4105 uses LTE-M and NB-IoT cellular communication, with automatic selection at installation. Rain data is transmitted to the SpecConnect cloud software platform and is also visible through the WatchDog Mobile App.
The station is designed for quick setup through the mobile app. Once activated, users can view current rain conditions remotely, supporting faster response and better coordination between field teams, municipal operators and site managers.

Built for simple deployment
The WatchDog 4105 is solar powered and designed for deployment wherever a compatible LTE-M signal is available. Its quick assembly, integrated power system and mobile app setup make it suitable for applications where rainfall data is needed at multiple remote or distributed sites.
Rain alerts by text, email or phone call allow users to follow key events without continuously checking the platform. This is especially useful for agricultural operations, municipal teams and site managers who need practical rainfall information in near real time.
A new entry point in the WatchDog 4000 Series
As a compact rain-focused station, the WatchDog 4105 provides an accessible entry point into remote rainfall monitoring. It is part of the broader WatchDog 4000 Series, a family of affordable stations intended for practical environmental and agricultural monitoring applications.
ES Canada supports Canadian users looking to deploy reliable rainfall monitoring for agriculture, municipalities, stormwater management, sports turf and distributed field operations. For projects requiring multiple monitoring points, the WatchDog 4105 offers a focused solution for remote rain data without the complexity of a full weather station.
