LJ18A3-8-Z-BX 8mm Inductive Proximity Sensor The LJ18A3-8-Z/BX proximity sensor will detect large metal fields at an 8mm distance with great precision. This allows you to accurately measure the distance to an (aluminum) heated bed for example. If you are using a glass plate as your print surface, you can use aluminum foil right below the glass, which will also be detected by the sensor (mirrors however are not detected). The sensor is equipped with a small red detection LED, indicating a nearby object. The sensor has M18 threading and includes a nut for easy mounting to your 3D printer or CNC machine. The LJ18A3 is a PNP Normally Open (NO) type of proximity sensor. This means that the signal lead will output a positive voltage (same as the input voltage) when a metal mass is detected. When nothing is detected, the signal is equal to ground. Most modern 3D printer firmware has some sort of auto bed leveling procedure available, but you will need to enable it. You can use this sensor as the z_min_endstop for example, replacing your current end stop. Most firmware will also use the min end stop as a probe, but some allow a separate probe to be defined. This sensor operates at 5-36V, so as the signal voltage is the same as the input voltage, also the signal will be 5-36V. You will need to down-convert the voltage to an acceptable level for your electronics. Please see the linked schematic on how to connect this sensor to the end stop pins of your electronics board.

Waterproof Ultrasonic Sensor This Waterproof ultrasonic sensor is very similar to the Ultrasonic sensor which is found in cars. This Waterproof Ultrasonic Obstacle Sensor shows some important constructional advantages over the conventional sensors. It comes in two separate parts one being the transducer which is the sensing element and the other being the control board. The module is capable of providing information on the objects between the distance range of 250 mm to 4500 mm. The great advantage of using this Waterproof Ultrasonic sensor is you can put the sensing element far away from all the control circuitry. This Ultrasonic Distance Sensor is an industrial-grade sensor to measure distance. Interfacing with it is the same as another cheap ultrasonic sensor, but it offers better performance and is compatible with harsher environments and is waterproof too. There are many ultrasonic distance sensors on the market, but sometimes, this kind of sensor needs to work in vulnerable conditions.  It is very easy to use, a control port with a 10US above high level can wait for high-level output at the receiving port. An output can drive the timer when this port is low can read the timer value, this time for the location of the time can be distance measurement. Constantly cycle tests that can achieve the measurement of the value of your mobile. It allow us to measure the distance between stationary objects such as walls, floors or ceilings with unparalleled accuracy. These advanced technology-packed devices detect changes in humidity levels, temperature fluctuations and other environmental conditions that could compromise safety of our valuables stored inside buildings we own or manage.  The environmentally sealed waterproof bodies provide protection against dust particles while allowing full access to settings at all times making it very easy for anyone to use them even without technical knowhow. Iotcart's range of waterproof ultrasonic sensors guarantees high precision performance both indoors and outdoors regardless of how wet your environment gets - be it rainwater flooding waters from rivers or oceans!

Sharp GP2Y0D810Z0F Digital Distance Sensor It is one of Sharp's fastest distance sensors - with a sample rate of almost 400 Hz and is an attractive alternative to short-range phototransistors and longer-range analog distance sensors. Output is high normally and low when the sensor detects an object. This sensor only tells if the object's nearby - not how near or far the sensor is - so they're great for break-beam, obstacle detection, and object counting.This sensor comes with a 3-pin male header and a 3-pin right-angle male header. You can connect these pins with a servo cable. The square pad is ground, the middle is VIN, and the remaining pad is output. If you place a large capacitor (more than 10uF) between power and ground you should see an increase in performance.
