4G Solution Kit

LoRaWAN® Solution Kit

It measures real-time photosynthetically active radiation across the radiation range from 400 to 700 nm. It contains a Silicon photodetector and generates a voltage signal directly proportional to the PAR under the light source, making it widely applicable in industrial environmental sensing scenarios.

 

We have three versions Industrial PAR Sensor. The main difference is the cable connector. Please choose the version that best suits your needs:

(1)This one is with a waterproof aviation connector. It is compatible with SenseCAP Sensor Hub 4G Data Logger, which can collect various sensor data simutaneously and send them via 3G/4G LTE.

(2)Another version is with hook-up wires,supporting MODBUS-RTU RS485 protocol, It is compatible with SenseCAP LoRaWAN® Data Logger to easily connect with the LoRaWAN® network, enjoying the benefits of low-power and long-range communication.

(3)Another version supports 2.5V analog voltage output.

Features

  • Easy To Use: Compact size, simple installation, quick integration
  • High performance: high accuracy, fast response, and superior stability
  • Strong Robustness: It's watertight and dustproof with IP66 Enclosure, and can operate under a wide range of temperatures from -30°C to 75°C
  • Supports universal MODBUS RS485 protocol: Can be easily connected to MODBUS-RTU RS485 data loggers.
  • Wide-range Power Supply: Can be powered with supply voltage within 5~24V DC

Description

Sunlight has a tremendous impact on the lifecycle of almost all creatures on this planet. For plants as an example, light is a key factor in photosynthesis reaction that matters to their survival. Different species of plants, and even different growth stages of the same species would require different degrees of light duration, exposure, strength, and radiation range. Sensors are thus a useful tool to help effectively control essential parameters, like photosynthetically active radiation (PAR), contributing to the success of research or agricultural activities.

 

The industrial-grade PAR sensor monitors the PAR in environments with natural light sources across a radiation range from 400 to 700 nm and provides important parameters for researchers and farmers. When there's light in, the sensor generates a voltage signal directly proportional to the PAR under the light source. You can obtain the measurement value in a unit of μmol/m2•s. The instrument supports the MODBUS-RTU RS485 protocol, you also can directly connect this PAR sensor with RS485 data loggers or digital voltmeters to create monitoring systems that meet your own demand.

 

This PAR sensor is robust with an IP66 enclosure and is able to withstand a wide range of temperatures from -30°C to 75°C, unlocking applications in harsh outdoor environments to support photosynthesis, solar, and ecological research, as well as the sensing in smart agriculture, greenhouse farming, tourism, meteorology, etc.

 

Seeed also provides the SenseCAP Portal and SenseCAP Mate to help users better manage and check data remotely.
