SenseCAP Combo 5-in-1 Environmental Sensor with 4G - Seeed Studio 100035616

Description

5-in-1 environmental sensor with 4G Cat.1 cellular connectivity, designed for microclimate monitoring in greenhouses, agricultural facilities, warehouses, and research installations. The SenseCAP Combo 4G-YUN-03-Global variant integrates air temperature and humidity, atmospheric pressure, light intensity, and carbon dioxide (CO₂) measurements. The device automatically collects measurements and transmits them over a cellular network, eliminating the need for wired network infrastructure. The CO₂ sensor has a measurement range of 0 to 10,000 ppm, while the light intensity sensor covers 0 to 200,000 lx, allowing environmental conditions to be analyzed in growing facilities and other monitored areas.

The RS485 interface with the Modbus RTU protocol allows the system to be expanded with up to 10 external sensors using a suitable splitter. Additional environmental parameters can be monitored depending on the connected devices. External sensors can use 5 V / 0.35 A and 12 V / 0.35 A power outputs. Connecting sensors that require 12 V power requires an external DC power supply.

The 4G Cat.1 modem and MQTT protocol enable data transmission to the SenseCAP Cloud platform or a custom MQTT server. Measurements can be viewed through the SenseCraft app and the SenseCAP Portal platform. If cellular connectivity is interrupted, the device stores up to 500,000 records locally and automatically uploads the buffered data when the connection is restored. Local measurement history export and over-the-air (OTA) firmware updates are also supported.

The SenseCAP Combo is suitable for monitoring greenhouse growing conditions, controlling microclimates in livestock buildings, and tracking temperature, humidity, and CO₂ concentration in warehouses. Environmental data logging enables the analysis of changes over time, comparison of conditions across different locations, and preparation of data for agricultural automation systems. The RS485 interface allows integrated measurements to be combined with data from additional sensors, such as those used to assess soil conditions. The device can also be used in educational and research projects involving microclimate analysis, environmental measurements, and Internet of Things (IoT) applications.

The built-in solar panel with a maximum output of 1 W and a 5200 mAh / 3.7 V Li-Ion battery enable operation in locations with limited access to mains power. According to the manufacturer, the device can operate for more than two weeks without solar charging, although actual operating time depends on measurement settings, transmission frequency, and connected sensors. An additional 5 V / 2 A external power input via USB-C is also available. The modem uses a Micro SIM (3FF) card, supports APN configuration, and features an integrated antenna. MQTT server settings, reporting intervals, and expansion configuration can be adjusted using the Sensor Hub Configuration Tool NG.

The PC/ASA enclosure with an IPX5 protection rating and F1 UV resistance protects the electronics against water jets and environmental exposure typical of greenhouse installations. The device can be installed in a hanging position or mounted on a pole using additional mounting accessories. Its dimensions are 202 x 202 x 175 mm, and it weighs approximately 0.8 kg. The permitted operating temperature range for the complete device is 0°C to 40°C. The included power adapter is intended for indoor use only and must be installed in a suitably protected enclosure when used outdoors. Further information is available in the SenseCAP Combo technical documentation and the getting started guide.
