This sensor buffers a piezoelectric transducer. As the transducer is displaced from the mechanical neutral axis, bending creates strain within the piezoelectric element and generates voltages. This sensor works on 5v. It gives Digital high (5V) output whenever vibration is detected. The Vibration Sensor Detector is designed for the security practice When Vibration Sensor Alarm recognizes movement or vibration, it sends a signal to controller.

APPLICATIONS

Ear thermometer: fast and easy fever measurement

Body temperature monitoring: monitoring the temperature of patients during operation or people in intense physical effort (athletes, firefighters, soldiers).

Home healthcare: measuring temperature in home use health equipment, 24/7 body temperature tracking

Mobile telephones: The MLX90615 is so small and easy to integrate, it can easily fit into handheld devices

The most prominent application for infrared thermometers, from Melexis, is measuring body temperature to check for fever and illness. There are three main types of IR fever thermometers: ear thermometers, forehead thermometers, and non-contact, distance-read thermometers. Measurement accuracy depends on the calibration accuracy of the thermometer and how accurately the temperature measured on the patient's exterior can be translated into an internal body temperature. For most medical applications, a measurement accuracy of ±0.2°C or better is required.

The MLX90615 from Melexis is the world's first intelligent infrared thermometer integrated into the ultra small TO-46 package commonly used in the manufacture of ear thermometers. This ultra-small and cost effective, non-contact thermometer delivers a fully calibrated digital temperature reading achieved by integrating an infrared sensor with a custom signal conditioning chip in a TO-46 package.

The sensing element in the MLX90615 is a silicon chip with a thin, micro-machined membrane heated by the infrared radiation of the object. This proven Melexis technology has been applied to industrial and automotive temperature measurement challenges for many years. A custom built signal conditioning chip amplifies and digitizes the minute voltages generated by the thermocouples on the sensor membrane and calculates the object temperature using factory set calibration parameters stored in the memory of the chip. The digitized temperature is fully linearized and compensates for ambient temperature. This high level of integration makes the MLX90615 very cost effective compared with previous infrared solutions.

mpu6050 has MEMS accelerometer and MEMS gyro with complete 6-axis motion tracking in a single package. It has 16-bits analog to digital conversion hardware for every channel, which helps to capture X, Y and Z axis or channel at the same time and it is very accurate. This module is compatible with Arduino, AVR, PIC, ARM, Raspberry Pi, and any other processor and controller and uses a 12C bus to the interface.

Most PTC thermistors are of the "switching" type, which means that their resistance rises suddenly at a certain critical temperature. The devices are made of a doped polycrystalline ceramiccontaining barium titanate (BaTiO₃) and other compounds. The dielectric constant of this ferroelectric material varies with temperature. Below the Curie point temperature, the high dielectric constant prevents the formation of potential barriers between the crystal grains, leading to a low resistance. In this region the device has a small negative temperature coefficient. At the Curie point temperature, the dielectric constant drops sufficiently to allow the formation of potential barriers at the grain boundaries, and the resistance increases sharply. At even higher temperatures, the material reverts to NTC behaviour. The equations used for modeling this behaviour were derived by W. Heywang and G. H. Jonker in the 1960s.

Another type of PTC thermistor is the polymer PTC, which is sold under brand names such as "Polyswitch" "Semifuse", and "Multifuse". This consists of a slice of plastic with carbon grains embedded in it. When the plastic is cool, the carbon grains are all in contact with each other, forming a conductive path through the device. When the plastic heats up, it expands, forcing the carbon grains apart, and causing the resistance of the device to rise rapidly. Like the BaTiO₃ thermistor, this device has a highly nonlinear resistance/temperature response and is used for switching, not for proportional temperature measurement.

Yet another type of thermistor is a silistor, a thermally sensitive silicon resistor. Silistors employ silicon as the semiconductive component material. In contrary to the "switching" type thermistor, silistors have an almost linear resistance-temperature characteristic.

18-D80NK Infrared Obstacle Avoidance Sensor contains an infrared transmitter and receiver which together make up a photoelectric sensor. The sensor has a long detection distance, and has less interference by visible light because it uses modulated Infrared light. This sensor has a screwdriver adjustment to set the detected distance, then gives a digital output when it senses something within that range. This sensor does not return a distance VALUE. It has 3 connecting wires:

    Red: +5 VDC
    Black: Ground
    Yellow: Output-Open collector pulldown( Use 10K pullup resistor to +5V)

It is widely used in robot obstacle avoidance, and many other automation products. The technology behind this effective distance sensor is modulation of infrared light. The receiver is sensitive only to infrared light. Therefore it is not very sensitive to ambient light compared to plain infrared detectors.
