How does it work?

CHESTER Range is a configurable distance sensor that uses the MaxBotix MB7066 ultrasonic sensor to accurately measure from 0.2 to 10 meters with a 1 cm resolution.

It supports up to four DS18B20 external temperature sensors (depending on the variant), allowing you to combine distance measurement with temperature monitoring.

The device has the following key features:

Wireless connectivity:

• LTE-M, NB-IoT, or LoRaWAN for data transmission from remote locations.

Power supply:

• Battery operation (7700 mAh, up to 5 years) or external power (6-28V DC) with battery backup on the Range Z model.

Built-in sensors:

• Thermometer to measure the internal temperature of the device.
• Accelerometer to detect change in position or handling.
• ADC battery measurement for power monitoring and maintenance.
• Local configuration via Bluetooth using our HARDWARIO Manager app.

Why is it important?

The CHESTER Range combines distance, temperature, and humidity measurement with low power consumption and long endurance. This makes it ideal for applications where a fixed power supply is not available or long-distance wireless monitoring is required.

Typical applications.

The CHESTER Range is ideal for a wide range of applications in industry, agriculture, and public administration. Its accurate distance measurement, multi-sensor support, and long battery life help optimize processes and reduce operating costs.

Agriculture

- Monitoring grain levels in silos - accurate real-time measurement of inventory levels helps optimize logistics and minimize losses.

- Monitoring temperature and humidity in warehouses - protecting crops from spoilage and better-managing storage conditions.

- Water level monitoring in irrigation areas - more efficient management of water resources.

Water Management

- Measuring water levels in reservoirs, wells, and retention systems - provides early warning of water shortages or overflows.

- Detection of groundwater levels - useful for geological surveys and water resource management.

- Monitoring sewer systems, preventing blockages, and efficiently maintaining infrastructure.

Transport and logistics

- Parking space occupancy detection - optimizing traffic management in cities and commercial zones.

- Monitoring the presence of objects in transport infrastructure, including the height of bridges, tunnels, and safety zones.

- Logistics warehouses and pallet storage - control of free space and more efficient use of storage capacity.

Waste management

- Monitoring the level of waste pits and containers - optimizing collection routes and reducing operating costs.

- Monitoring waste levels in industrial plants - better waste disposal planning and reduction of environmental burden.

- Automated management of collection points - digitization of waste management for municipalities and private companies.

Available CHESTER Range variants

The CHESTER Range is available in several variants that allow it to be adapted to different applications:

• CHESTER Range - Battery version.
• CHESTER Range Z - External power supply (6-28V DC) with battery backup option.
• CHESTER Range H - Measurement of temperature and humidity using the external CHESTER-S2 sensor.
• CHESTER Range 1W - Support for up to four DS18B20 temperature sensors to measure distance and temperature simultaneously.

With its flexibility and robust design, the CHESTER Range is the ideal solution for industrial and environmental applications where measurement accuracy and reliable data transmission are key.
