BIQU Filament Break Detection Sensor Module 3D Printer Accessories with 1M Cable for 1.75mm Filament Extruder Material Run-Out Detector for 3D Printer (Transparent)

  • ❤【Function of Filament Detection Module】 To detect Filament in 3D printer run-out,pause detection,it automatically stops the 3D Printer when the filament runs out.Optimize the inlet port/outlet port of the material detection module, to reduce the resistance of the feeding material..
  • ❤【Filament Break Detection Module】When there is material, the level signal of the detection port should be high level. When there is no material, the level signal of the material port goes low, and the system detects one. If the high-to-low transition is determined, the material is considered exhausted and a pause command is executed..
  • ❤【Detection Method】The material detection module uses the level jump detection method..
  • ❤【Filament Size】 It Suitable for 1.75mm Filament with 1m cable which making your printing work goes smooth and relieved..
  • ❤ 【After-Sales Guarantee】We support high quality after-sales Service,any questions or feedback please contact us,no matter what refund or resend. We will satisfy with your request..

Tangyy 5pcs HC-SR04 Ultrasonic Sensor, Distance Sensor with Ultrasonic Transmitter and Receiver Module fit for Raspberry Pi,MEGA2560, Robot (Blue)

  • Widely used: Sweepers, DIY robot cars, for raspberry pi project,It can be building a little robot to measure distances in a room under construction.
  • HC-SR04 Ultrasonic Sensor Module: It measures distance by sending out a sound wave at a specific frequency and receiving back that sound wave to bounce.
  • Good Accuracy: Power Supply :3V-5.5V DC, Detection angle: 003c15 °, Minimum target distance is 2.0cm from the end of the Voltage transducers. Maximum repeatable target distance is 2CM-150CM for a large unobstructed stationary target.
  • Easy to install: There are 4 pins out of the module, VCC supply 5V, and GND is ground wire. TRIG is trigger control signal input, ECHO is echo signal output, So it's a very easy interface for controller to use it ranging.
  • Note: The module should be inserted in the circuit before been powered to avoid producing high level of Mis-operation.

AIHJCNELE RCWL-0516 Microwave Radar Sensor Switch Module Human Body Sensing Board Intelligent Induction Detector Motion Detection 5-7M for Arduino ESP8266 Nodemcu Better Than HC-SR501 (RCWL0516 6pcs)

  • R60ABD1 radar module is the use of 60G millimeter wave radar technology, detection of human skin subtle changes, through the algorithm to calculate the respiratory frequency, heartbeat frequency, motion amplitude, abnormal activity information.
  • Secondary development information: 1) Radar built-in algorithm processor, direct output results, no need for cloud computing 2) The detection results of radar are output by SCM serial protocol 3) Communication module (WiFi, 4G, etc.) is not included in the design of radar module.
  • Detection range: 1) Trigger range and accurate detection range of yunfan radar calibration 2) The maximum accurate detection range is usually within 40 degrees conical Angle within the design range of radar antenna.
  • 3) The radar detection range can be adjusted by adjusting the Angle and distance 4) The detection accuracy is closely related to the detection target distance.
  • Usage: 1) Installed in a fixed position, accurate detection of external moving objects 2) Radar penetrates low density objects such as thin wooden planks. Caution False positives are caused by large detection range 3) Due to different electromagnetic wave noise in different environments, electromagnetic environment at the bottom of radar is required in some cases.
