ES108
  1.  Integrated Outdoor Weather Station - Temperature, Humidity, Noise, Atmospheric Pressure, Illumination, Wind Speed/ Direction, Rain, Solar Radiation, CO2 or PM2/10 Sensor

The ES108 is a compact, lightweight, all-in-one outdoor environmental sensor unit designed to support a broad range of monitoring applications. It integrates multiple sensor types, including temperature, humidity, noise, atmospheric pressure, wind speed and direction, illumination, rainfall, solar radiation, and either CO₂ or PM2.5/PM10 concentrations. Sensor modules can be flexibly configured based on user-specific measurement requirements. Data output is provided via an RS-485 interface using the Modbus protocol. The unit is housed in a lightweight louvered radiation shield, featuring adjustable height and a waterproof PG7 cable gland for enhanced pull resistance. Its integrated die-cast waterproof connector with interlocking design ensures long-term durability, offering resistance to UV exposure, heavy rain, freezing temperatures, corrosion, and rust. The ES108 supports a 10–30VDC power input and is easily mountable on pole tops with the installation kit. When connected to optional communication gateways—such as the WR222 NB-IoT/WiFi gateway, LC144 LoRa end node, or SCB111-RS485 NB-IoT outdoor gateway—real-time monitoring and data visualization can be achieved via cloud platforms. The ES108 is ideally suited for agricultural, residential, and industrial environmental monitoring, as well as remote weather station deployments.

  • Ultrasonic Wind Speed and Direction sensor uses four ultrasonic transducers arranged in a two-dimensional plane to alternately transmit and receive signals. By measuring the time difference of ultrasonic wave propagation in air, it accurately determines wind speed and direction.
  • Noise- High-sensitivity capacitive microphone with a built-in electret condenser as the sound sensing element, the device performs sound intensity measurement with stable signals and high accuracy
  • Atmosphere Pressure- The atmospheric pressure transmitter consists of a sensing element and a microprocessor. The sensing element applies the measured pressure to a specific surface area, converting it into displacement or strain. This is then converted into an electrical signal proportional to the pressure by a displacement-sensitive component or strain gauge.
  • PM2.5/PM10- Using the laser scattering principle with a built-in fan as the airflow driver, the sensor features an integrated insect-proof mesh to prevent insects from interfering with the measurement, ensuring accurate and reliable data.
  • CO2- Utilizes NDIR (Non-Dispersive Infrared) technology for CO₂ concentration measurement. It features dual-channel detection, including both a measurement and a reference channel, significantly enhancing data accuracy and consistency—outperforming common single-channel products on the market.
  • Illumination- Illuminance is measured using a high-precision photosensitive transmitter, with output values expressed in Lux.
  • Solar Radiation- The device adopts a high-precision photosensitive sensor with broad-spectrum absorption, capable of measuring solar radiation in the spectral range of 0.3 to 3 μm.
  • Rain- The device uses an optical sensing principle to measure rainfall, with multiple built-in optical probes ensuring reliable detection. Unlike traditional mechanical rain sensors, the optical rain sensor is more compact, highly sensitive and reliable, smarter, and easier to maintain.
