Cảm biến nhiệt độ kỹ thuật số DS18B20 không thấm nước DS18B20

Sản phẩm này là phiên bản chống nước của cảm biến nhiệt độ DS18B20 1 dây TPE overmolding cho Arduino, được thiết kế đặc biệt để đo nhiệt độ trong môi trường xa hoặc ẩm ướt. Cảm biến nhiệt độ kỹ thuật số này có dải nhiệt độ rộng từ IP68 -55°C đến 125°C, but we recommend keeping the included PVC / TPE jacketed cable below 110°C to ensure optimal performance and durability.

All weather/submersible digital temperature probe, specifically designed to be used in the field Arduino. This sealed digital temperature probe lets you precisely measure temperatures in wet environments with an advantage over linear temperature sensors calibrated in Kelvin, as the user is not required to subtract a large constant voltage from the output to obtain convenient Centigrade scaling.

The overmolding DS18B20 waterproof temperature sensor is a digital sensor that maintains signal integrity even over long distances. It utilizes a 1-Wire interface, connecting to a central microprocessor through a single wire (along with a ground wire). This design simplifies installation and connection, making it particularly suitable for arduino systems operating within the 3V~5.5V range.

Waterproof DS18B20 temperature sensor plug, cụm đầu nối

Each DS18B20 temperature sensor has a unique silicon serial number, useful for verifying its authenticity and enabling the connection of multiple sensors on a single 1-Wire bus. This feature facilitates the installation of temperature sensors in various locations for applications like indoor temperature monitoring, smart home integration, object temperature detection, greenhouse farming, and more.

With our plugable terminal, there is no soldering required to connect to our IO Expansion Shield. This allows you to conveniently integrate the DS18B20 temperature sensor into your project, saving you time and effort.

This is a pre-wired and waterproofed version of the DS18B20 sensor all weather/submersible temperature probe, specifically designed to be used in the field.

The DS18B20 does not require any external calibration or trimming to provide typical accuracies

Multiple thermometers can be connected on the same wire because every one has it’s own internal address.

Technical performance
1. Mô tả hiệu suất kỹ thuật:
①. Unique single-wire interface mode. When DS18B20 is connected to a microprocessor, it only needs 1-Wire to realize two-way communication between the microprocessor and DS18B20.

②. Phạm vi đo nhiệt độ: -55oC～+125oC, inherent temperature measurement error (ghi chú, not resolution, it was wrong before) 1oC.
③. Support multi-point networking function. Multiple DS18B20 can be connected in parallel on the only three wires, and up to 8 can be connected in parallel to realize multi-point temperature measurement. Nếu số lượng quá lớn, the power supply voltage will be too low, resulting in unstable signal transmission.
④. Working power supply: 3.0~5.5V/DC (data line parasitic power supply can be used).
⑤. No peripheral components are required during use.
⑥. The measurement results are transmitted serially in 9~12-bit digital quantity mode.
⑦. The diameter of the stainless steel protective tube is Φ6.
⑧ 、Applicable to temperature measurement of industrial pipelines of various media of DN15~25, DN40~DN250 and equipment in narrow space.
⑨、Standard installation thread M10X1, M12X1.5, G1/2” optional.
⑩ 、Overmolding PVC cable direct outlet or German ball-type junction box outlet, easy to connect with other electrical equipment. DS18B20+ and Maxim Integrated Information Manufactured by Maxim Integrated, DS18B20+ là cảm biến nhiệt độ.
