Hall Effect Sensor The RM0435 Sensor is an integrated Hall Effect latched sensor. Holding a magnet near the sensor will cause the output pin to toggle. This makes for a robust presence sensor. A reed sensor also works nicely, but can be limited by the glass encapsulation and size. A Hall Effect sensor is much smaller, but can handle less current than a reed switch.Thanks to its wide operating voltage range and extended choice of temperature range, it is quite suitable for use in automotive, industrial and consumer applications.The device is delivered in a Thin Small Outline Transistor (TSOT) for surface mount process and in a Plastic Single in Line (TO-92 flat) for through hole mount. Both 3-lead packages are RoHS compliant. The output signal of this sensor is open-drain type. Such output allows simple connectivity with TTL or CMOS logic by using a pull-up resistor tied between a pull-up voltage and the device output.The device includes an on-chip Hall voltage generator for magnetic sensing, a comparator that amplifies the Hall voltage, and a Schmitt trigger to provide switching hysteresis for noise rejection, and open-collector output. An internal band gap regulator is used to provide temperature compensated supply voltage for internal circuits and allows a wide operating supply range.If a magnetic flux density larger than threshold Bop, DO is turned on (low). The output state is held until a magnetic flux density reversal falls below Burp causing DO to be turned off (high). The RM0435  exhibits latch magnetic switching characteristics. Therefore, it requires both south and north Poles to operate properly.

Hall Effect Sensor Module Hall Effect Sensor Module is used to detect the proximity of a magnet. It is very much smaller in size. When the magnetic field rises above a threshold level, the open-collector output transistor switches on, which pulls the logic-compatible output low and illuminates the onboard LED indicator. It's fast (The turn-on threshold is 35-450 Gauss, the minimum hysteresis is 20 Gauss, and the operating voltage range is 4.5 - 24 volts. This module uses the Allegro MicroSystems A3144EUA sensor. It has a 3-pin interface, signal, V+, and GND. To use this sensor/switch, place a 10K pull-up resistor between the "S" pin and the middle pin (+), and connect the "-" pin to the ground. Supply voltage to the middle pin. The "S" pin will go low (gets pulled to the ground) and the onboard LED indicator will turn on when a magnet is brought near.

Tilt Sensor Tilt sensors allow you to detect orientation or inclination. They are small, inexpensive, low-power and easy-to-use. If used properly, they will not wear out. Their simplicity makes them popular for toys, gadgets and appliances. This sensors is a solution for where you need detect when something has shifted from it’s desired orientation. It’s a simple ball-in-a-sleeve that when rolled to one end closes a contact. Actually, it’s a pair of balls, the second ball reinforces the bridging of the contacts by the first ball. In it’s simplest application, it could be hung straight down and would close only if it were swung over 90° in any orientation. Team up 2 or 3, adjust the angles, and you could have it report when orientation shifts past any one of their angles. Sort of a really poor-man’s gyro/g-force sensor. Note: The orientation of the pins will affect the responsiveness of the sensor. Laid horizontally, the balls will bridge the sensor pins much more easily than if the pins are laid vertically. check out : KY-010 Broken Light Blocking Sensor Applications: To detect the position of hand-held game systems and in game controllers To indicate the roll of boats, vehicles and aircraft To measure the angle at which a satellite antenna 'looks' toward a satellite To estimate the height of a tree or building To measure the steepness of a ski slope To provide a warning system for the surface tilt angle of cryogenic liquids during transportation To monitor laser levels and seismic activity Package Includes: 1 x Tilt Sensor Specifications Voltage < 12V Current < 20ma Differential angle 15 degree Contact Resistance <10 ohm Insulation Resistance >10M ohm Dimensions  12.2mm length x 5.4mm diameter cylinder Weight  5 grams

Tilt Sensor Module The Tilt Sensor Module for Arduino comes with the basic components for operation. Supplying power and it is good to be used. Attach the inclinometer sensor to an object and it will detect whether the object is tilted. Simple usage as it is the digital output, so you will know whether the object is tilted or not by reading the output. It uses SW-460D or SW-520D tilt sensor. The Tilt Sensor is the ball rolling type, NOT Mercury type. The tilt sensor Comes with an M3 mounting hole for ease of attaching it to an object. Onboard, it provides a tilt switch, high sensitivity and commonly being used for tilt detection. The module comes with a power LED and a status LED for the visual indicator. Module instructions: The switch output of the module depends on the on and off of the angle switch. When the angle switch is off, the DO output is high, and when the angle switch is turned on, the DO output is low. The output terminal can be directly connected to the single-chip microcomputer, and the high-low level is detected by the single-chip microcomputer, thereby detecting the angle change. The output terminal can directly drive the relay module, which can form a high-power angle switch to protect the automatic power-off function when the products such as electrical equipment are dumped. Connecting a Tilt Sensor Module to an Arduino- Connecting a tilt sensor module to an Arduino is a simple process that can be done by following the steps below: Insert the tilt sensor module onto the breadboard or PCB, taking care to align the pins. Connect the tilt sensor module's power and ground pins to the Arduino board's power and ground pins. Connect the tilt sensor module's output pin to one of the Arduino board's digital input pins. To read the data from the tilt sensor module, upload a sketch or software to the Arduino board. The sketch may utilise the digitalRead() method to read the state of the input pin and calculate the tilt sensor angle. After uploading the programme, you can test the tilt sensor module by tilting it in different directions and seeing the output on the Arduino.

Vibration Sensor Module Vibration sensor module alarm Motion sensor module vibration switch SW-420 module based on the vibration sensor SW-420 and Comparator LM393 to detect if there is any vibration that beyond the threshold. The threshold can adjust using an onboard potentiometer. When this no vibration, this module output logic LOW the signal indicates LED light, and vice versa. If the module does not vibrate, the vibration switch was closed on state, the output of low output, and the green indicator light. The product vibrates, vibration switches momentary disconnect, the output is driven high, and the green light does not shine. The output can be directly connected to the microcontroller, which detects high and low levels, so as to detect whether the environment exists vibration, play a role in the alarm. It is useful for a variety of shocks triggering, theft alarms, smart cars, an earthquake alarms, and motorcycle alarm. This module when compared with a normally open pneumatic shock sensor module, shock triggered much longer can drive relay module the use of the company’s production of SW-420 normally closed type vibration sensors.
