How it works: The material detection module uses the level jump detection method: When there is material, the detection level level signal should be high level, no material, the material port level signal becomes low level, the system detects a certain high Level to low level of the jump, then that the material exhausted, the implementation of the suspension of the order, waiting for the replacement of good material after the implementation of continuous printing. Features: Feeding mouth and outlet at the same time to increase a wear-resistant copper sets. Can effectively extend the product life.
This is a waterproofed version of the DS18B20 Temperature sensor for Arduino. Handy for when you need to measure something far away, or in wet conditions. While the sensor is good up to 125 degree, the cable is jacketed in PVC keeping it under 100 degree Celsius. This sensor provides 9 to 12-bit (configurable) temperature readings over a 1-Wire interface, so that only one wire (and ground) needs to be connected from a central microprocessor.Usable with 3.0-5.5V systems.
DS18B20 Maxim/Dallas Semi digital thermometer provides 9-bit to 12-bit Celsius temperature measurements and has an alarm function with nonvolatile user-programmable upper and lower trigger points. The DS18B20 communicates over a 1-Wire bus that by definition requires only one data line (and ground) for communication with a central microprocessor. It has an operating temperature range of -55°C to +125°C and is accurate to ±0.5°C over the range of -10°C to +85°C. In addition, the DS18B20 can derive power directly from the data line ("parasite power"), eliminating the need for an external power supply.
