1 Product Introduction

SenseCAP ONE is a series of all-in-one compact weather sensors, including S900 9-in-1, S700 7-

in-1, and S500 5-in-1 weather sensors. These weather sensors integrate multiple sensors into this

compact device, monitoring up to 9 weather parameters: air temperature, air humidity,

atmospheric pressure, light intensity, wind speed, wind direction, precipitation, PM 2.5, and PM

10. The sensors use ultrasonic to measure wind speed and wind direction, to achieve high-

precision data collection, which is easy maintenance. The equipment is designed with industry

standards and can work stably in harsh outdoor environments from -40°C to 85°C. The product

supports the Modbus-RTU (RS232/RS485/RS422), ASCII, and SDI-12 protocol.

Installation

2.2.1 Device Interface Introduction

There are two connectors at the bottom of the device.

• USB Type-C interface allows you to connect your computer with a normal USB Type-C cable

to the device for configuration.

• The main data interface can be connected to the M12 8-pin cable, supporting multiple bus

protocols

2.2.2 Connect with USB Cable

2.2.3 M12 Cable

The device adopts an M12 8-pin connector, the different colored pins provide power and data

communication (as shown in the above diagram).

When working with the RS-485, you can connect only 4 wires (not using a heating function), and

the rest can be individually wrapped with tape to prevent short circuit

The holes of the cable and the pins of the device connector must be aligned when the cable is

plugged in.

Plugin the cable and tighten it clockwise

User manual/ Technical information

When using the device with a heating function, a separate 12V-24V (12V@2A is recommended)

power supply is required. Gray wire #5 is connected to the negative of the power supply, and

pink wire #6 is connected to the positive pole of the power supply.

2.2.4 Install the device.

There are two major installation methods, either mount on a pole with a sleeve or a platform

with a flange plate.
