Compact Weather Station & Environmental Monitoring

A weather monitoring setup built on the SenseCAP S700 7-in-1 station and a 4G data logger, sending readings to the SenseCAP cloud for dashboards and alerts. It is aimed at farms, greenhouses, solar parks and industrial sites that need warnings for wind, rain and temperature. A Wio Terminal starter kit lets a team try the data flow and alert rules on a desk before buying field hardware.

The problem

Why it matters.

Farms, solar sites and labs need continuous local weather data and storm alerts without running cables.

7 parameters from one station with no moving parts to wear
IP66 housing; logger accepts 12 to 24 V DC for solar setups
Dashboards and rules carry over unchanged from starter kit to industrial station

The flow

From signal to action.

01SenseWeather sensingThe S700 measures wind speed and direction, rain, pressure, temperature, humidity and light with no moving parts.
02Connect4G loggerThe Sensor Hub 4G reads the station over RS485 Modbus-RTU and sends the data over cellular, caching it during outages.
03RecordCloud platformSenseCAP PaaS stores readings and shows live values, 24-hour trends and device health.
04ActAlerts and outputsRules send SMS, webhook or chat alerts and can switch drainage pumps, irrigation or shading.

How it works

Step by step.

01Mount the S700 outdoors and connect it to the Sensor Hub 4G with the supplied M12 cable.
02Power the logger from a 12 to 24 V DC supply, which can be a solar setup.
03The logger sends readings over 4G and fills in any gaps once the link returns.
04Set alarm rules for gusts, storms and temperature extremes in the SenseCAP Portal.
05Pull data into SCADA, Home Assistant or your own software through the API, webhooks or MQTT.

Before you install

A 12 to 24 V DC supply for the logger, which can come from an off-grid solar panel.
Usable 4G mobile signal at the station, plus a data SIM for the logger.
An open mast or pole where wind and rain are not blocked by buildings or trees.
A cable run between station and logger. RS485 handles long runs well and M12 cabling comes in the package.
2.4 GHz Wi-Fi only if the starter kit is linked to Home Assistant or the cloud.

Good to know

The page gives no measurement ranges, accuracy or calibration intervals for the S700, so ask for the datasheet before quoting.
The Wio Terminal kit is for desk testing only and is not built for outdoor use.
Alerts depend on the cloud link. Data is cached during an outage, but alerts may be late until 4G returns.
No prices or ongoing platform costs are listed.

How we deliver it

Paper to site, one team.

01Site surveyWe walk the site, or review photos and drawings, and agree what to measure and where each device goes.
02PilotOne lane, one line or one room first. We tune it on your conditions and agree what good looks like.
03Roll outWe supply the hardware in India with GST invoices, install it, and connect it to the systems you already run.
04SupportSpares, remote checks and model updates, with one team to call when something changes.

Questions

Asked before buying.

Does it need mains power or Wi-Fi at the site?

No. The logger runs on 12 to 24 V DC, including solar, and sends data over 4G.

Can we connect the station to our own PLC?

Yes. The S700 can be bought on its own and speaks RS485 Modbus-RTU, which PLCs and industrial PCs read directly.

What happens if the mobile network drops?

The logger stores readings and uploads them when the connection comes back.
