Passive infrared (PIR) sensors use a pair of pyroelectric sensors to detect heat energy in the surrounding environment. The term 'NodeMCU' strictly speaking refers to the firmware rather than the associated development kits. The name 'NodeMCU' combines 'node' and 'MCU' (micro-controller unit). NodeMCU is an open-source firmware for which open-source prototyping board designs are available. Those measurements can be used to detect imbalances or other issues in the asset and predict future breakdowns. When the substrate is bent, the sensor produces a resistance output correlated to the bend radius-the smaller the radius, the higher the resistance valueĪ vibration sensor is a device that measures the amount and frequency of vibration in a given system, machine, or piece of equipment. They are commonly used to detect toxic or explosive gasses and measure gas concentrationĪs a variable printed resistor, the Flex Sensor achieves great form-factor on a thin flexible substrate. Gas sensors (also known as gas detectors) are electronic devices that detect and identify different types of gasses.

It includes an alarm system, a natural gas line, propane & a fire suppression system.

The flame detection response can depend on its fitting.

“ZIGBEE” stands for a Zonal Intercommunication Global-standard, where Battery life is long, which is Economical to deploy, and which exhibits Efficient use of resources.Īn ultrasonic sensor is an instrument that measures the distance to an object using ultrasonic sound waves.Ī flame sensor is one kind of detector which is mainly designed for detecting as well as responding to the occurrence of a fire or flame. Also, HC05 can act as both master and slave whereas HC06 functions only as a slave. GPS modules contain tiny processors and antennas that directly receive data sent by satellites through dedicated RF frequencies.īoth the modules are the same in functionality except the pinout. Arduino can interact with buttons, LEDs, motors, speakers, GPS units, cameras, the internet, and even your smartphone or your TV. The Arduino hardware and software were designed for anyone interested in creating interactive objects or environments.
