SensMax SensGuard DS18B20 Wireless Temperature Sensor with Probe

The remote temperature sensor with probe SensMax DS18B20 is a wireless device designed for accurate monitoring in a range from -30°C to +120°C. It delivers ±0.5°C accuracy with 0.1°C resolution, making it ideal for precise monitoring in cold storage, HVAC systems, and industrial applications. Powered by two standard AAA batteries, the sensor provides up to 5 years of operation without replacement.

How It Works

The DS18B20 uses a 1 m probe that can be mounted in freezers, ducts, or other hard-to-access areas to capture accurate readings. Data is collected every 5 minutes and transmitted via secure wireless protocol to a SensMax gateway within a 150 m range. The gateway aggregates information from up to 250 probe temperature sensors and forwards it to the SensWeb online portal for reports, graphs, and alerts.

Installation

Mounting the temperature probe sensor takes only seconds using adhesive tape or a bracket. The 1 m probe makes it possible to measure temperature inside freezers, liquid containers, or HVAC ducts while keeping the sensor body accessible. Battery power ensures fully wireless operation for up to 5 years.

Key Technical Advantages

• Wide measurement range — from -30°C up to +120°C.
• High accuracy — ±0.5°C with 0.1°C resolution.
• Probe flexibility — 1 m probe for hard-to-reach places and liquid monitoring.
• Wireless setup — no cabling required, quick installation.
• Battery power — operates up to 5 years on two standard AAA batteries.
• Secure communication — AES128-encrypted wireless transmission up to 150 m.

Real-World Applications

• Supermarkets — track freezer and cooling unit performance to prevent food spoilage.
• Warehouses — monitor deep-freeze and cold storage rooms for compliance.
• Pharmaceutical storage — safeguard medicine and vaccine storage conditions.
• HVAC systems — measure temperature in ducts and detect equipment failures.
• Industrial processes — control heating and cooling in production environments.
• Liquid tanks — monitor water, chemical, or beverage temperatures via probe immersion.
• Museums — climate supervision for exhibits with embedded probe monitoring.
• Data centers — prevent overheating in server racks and rooms.

Business Impact

Deploying probe temperature sensors helps maintain safe conditions in industrial, storage, and retail facilities. Freezers, HVAC systems, and sensitive storage can be monitored in real time, reducing the risk of spoilage or equipment breakdown. Automatic alerts improve efficiency by enabling quick response to temperature deviations before costly losses occur.
