TLE4999I3 Hall Effect Sensors

TLE4999I3 Pinout

TLE4999I3 is a linear hall effect sensor that adjusts its output on the basis of whether a magnetic field exists or not. It generates an output signal depending on the magnetic field density around it. If the magnetic flow density around it reaches a certain pre-set threshold value, the sensor senses the magnetic field and … Read more

CCS811 Indoor Air Quality Gas Sensor

CCS811 pinout

CCS811 is an air quality sensor that senses different gasses present in the air we breathe. It has a metal oxide (MOX) sensor and a small microcontroller. The MOX sensor detects the volatile organic compounds and the microcontroller has an ADC converter that reads the analog values and an I²C interface to read from. This … Read more

BMP280 Barometric Pressure and Temperature Sensor Module

BMP280 Module

BMP280  is a high precision sensor module that measures the atmospheric pressure and temperature in air. Not only this, but it can also measure humidity in the air. This six-pin module supports both SPI and I2C interfaces. It uses a BMP280 barometric pressure sensor. These sensors are pre-calibrated, unlike other sensors. Therefore, they start measuring … Read more

HC-SR505 PIR motion sensor Module

hc-sr505 pir motion sensor

HC-SR505 is a pyroelectric motion sensor. All the objects having a temperature above absolute zero release heat energy. This energy is in the form of infrared radiation. Even human bodies emit infrared light radiations. HC-SR505 sensor detects the motions of the object by measuring the changes in the level of infrared light radiations that is … Read more

TMP36 Low Voltage Temperature Sensor

TMP36 pinout

TMP36 is a temperature sensor chip which generates an analog voltage at the output which is linearly proportional to the Celsius temperature. Then convert this voltage into temperature based on a 10 mV/°C scale factor. It has a shutdown capability which limits the output current to less than 0.5 µA. It provides a supply current … Read more

LM339 Quad Differential Comparator IC

LM339 pinout

LM339 is a quad differential comparator IC in which four independent voltage comparators reside inside a single 14- lead package. As it is a comparator IC, therefore it compares the two input values and generates the output depending on the comparison. All the comparators behave independently and hence they can perform different tasks at the … Read more

LM4558 Dual Operational Amplifier

LM4558 pinout

LM4558 IC is a monolithic integrated chip consisting of two operational amplifiers that belong to the LM series of integrated circuits. Although these two operational amplifiers reside in a single package, but they operate independently of each other. However, both operational amplifiers share the same power rails. The two op-amps have very low noise interference … Read more
