Apollo Waterproof Temperature Probe for PLT-1 and TEMP-1 Sensors

The Apollo Waterproof Temperature Probe is a versatile sensor that easily connects to the Apollo PLT-1 Ultimate Plant Sensor or TEMP-1 sensor . Thanks to its reliable DS18B20 technology and fully waterproof design, this probe is suitable for a wide range of applications: from soil and water temperature to refrigerator, freezer, and environmental measurements.

You can choose from two lengths: 20 cm (ideal for plant pots, aquariums, terrariums, or compact spaces) and 150 cm (perfect for deep containers, compost piles, large aquariums, or hard-to-reach areas). The 3.5 mm jack connection allows the probe to be plugged in and used directly with Apollo sensors.

Examples of applications:

• Soil temperature: Measure the temperature in potting soil, vegetable garden, greenhouse or compost heap.
• Water temperature: Ideal for aquariums, ponds, hydroponics or irrigation systems.
• Refrigerator & Freezer: Easily check the temperature in the refrigerator or freezer compartment.
• Ambient temperature: Measure the temperature in your house, garage, shed or server cabinet.
• Terrarium & Vivarium: Keep a close eye on the temperature for reptiles or exotic animals.

Key benefits:

• Choose from 20 cm or 150 cm: Always the right length for your situation.
• Completely Waterproof: Suitable for long-term use in soil, water or damp environments.
• DS18B20 technology: Wide temperature range (-55°C to +85°C) and high accuracy.
• Plug & play: Connect directly to Apollo PLT-1 and TEMP-1 sensors.
• Universally applicable: One probe for soil, water, refrigerator, freezer or environment.

Disadvantage:
Only the probe itself is waterproof; always keep the connection to the main unit of the sensor dry.

Ease of installation

Simply insert the probe into the desired location (ground, water, refrigerator, etc.), connect it to your Apollo sensor via the 3.5mm jack, and you can start measuring immediately. No tools required.

Practical applications for Dutch households:

• Measure soil temperature in a greenhouse, garden or vegetable garden.
• Check the water temperature in the aquarium or pond.
• Monitor the temperature in the refrigerator or freezer.
• Use in terrariums, server cabinets, or other temperature-sensitive environments.
• Choose the 150 cm version for deep bins or hard-to-reach places.
