It has a 64 bit read-only memory to store the serial number of the device, allowing up to 8 DS18B20 sensors to be connected in parallel on a single bus Communication is carried out on the board, greatly saving users 10 ports of MCU and other devices. A 10K resistor is pulled up inside the board, making it convenient for users to use on microcontrollers without pull-up function. The product comes with various models of microcontrollers such as for arduino, 51 microcontroller, STM32, and ESP32 as sample programs. Parameter Introduction Working voltage: 3.3/5V Communication interface: one-way (single bus) Temperature measurement range: -55 ° C~+125 ° C (-67 ° F~+257 ° F) Temperature measurement error: ± 0.5 ° C (-10~+85 ° C) ±2°C (-55~ + 125 C ) Interface model: PH2.0-3P (with 3P-PH2.0 to DuPont 2) 54 Female Head Wire) Positioning method: M3 screw Module weight: 6 9g Module size: 23 35mm (manually measured) V: Power supply positive, 3.3/5V G: Negative power supply, ground D: Single bus data communication port Precautions 1. The module is compatible with 3.3V and 5V power supply, and is equipped with a 10K pull-up resistor. It is recommended that users use the same voltage as the communication level for power supply. 2. The inner diameter of the fixed hole is slightly larger than 3mm, and users can use M3 screws or copper pillars to fix the module. Review: Reliable & Simple Sensors - These 3 temperature sensors work well with Arduino or Pi boards to get a basic accurate temperature measurement. The PCBs are a bit oversized for the actual modules, but that's better than a tiny delicate module. Overall if you need to add a temperature sensor to your embedded project this is a cheap simple way to get the job done. Review: They do what is advertized. - Quality of the board is great, Easy to break from the board they all come attached to. print on the boards is also of great quality. easy to read, simple to use. Had no issue using these on an ESP32. worked great with the standard sensorkit library from arduino. highly recommend if this fits your desired profile. ## Features - High Precision and Wide Range: The T Sensor DS18B20 Digital Thermometer Module offers accurate temperature readings from -55°C to +125°C, with an error margin of ±0.5°C, making it ideal for precise temperature monitoring in various applications - Single Bus Communication Simplified: This T Sensor DS18B20 module uses a single bus communication interface, allowing up to 8 sensors to be connected in parallel, saving valuable MCU ports and simplifying your project setup - Versatile Compatibility and Easy Integration: Compatible with 3.3V and 5V power supplies, the T Sensor DS18B20 is designed to work seamlessly with popular microcontrollers like for arduino, 51, STM32, and ESP32, ensuring easy integration into your projects - Convenient and Reliable Design: The T Sensor DS18B20 features a built-in 10K pull-up resistor and a PH2.0-3pin interface, providing a convenient and reliable connection.
