Last Blog I told the basic definition of IoT, Today we know the details about IoT architecture .


IoT Sensor :- 

A sensor is a gadget which distinguishes, measures and reacts to some kind of contribution from the physical condition.

Some popular sensors we used more time in IoT

DHT11 :- This sensor commonly used for measure Temperature and Humidity.
IoT  Sensors and Devices

DHT11 Specifications

  • Working Voltage: 3.5V to 5.5V 
  • Working current: 0.3mA (estimating) 60uA (backup) 
  • Yield: Serial information 
  • Temperature Range: 0°C to 50°C 
  • Dampness Range: 20% to 90% 
  • Goals: Temperature and Humidity both are 16-piece 
  • Exactness: ±1°C and ±1%


Ultrasonic Sensor :- This sensor is an instrument that estimates the separation to an article utilizing ultrasonic sound waves.

Ultrasonic sensors work by conveying a sound wave at a recurrence over the scope of human hearing. The transducer of the sensor goes about as a receiver to get and send the ultrasonic sound. Our Ultrasonic sensors, in the same way as other others, utilize a solitary transducer to send a heartbeat and to get the reverberation. The sensor decides the separation to an objective by estimating time slips by between the sending and getting of the ultrasonic heartbeat.

HC-SR04 Sensor Features

  • Working voltage: +5V 
  • Hypothetical Measuring Distance: 2cm to 450cm 
  • Down to earth Measuring Distance: 2cm to 80cm 
  • Precision: 3mm 
  • Estimating edge secured: <15° 
  • Working Current: <15mA 
  • Working Frequency: 40Hz
HC-SR505 PIR Sensor :-HC-SR505 is scaled down PIR (Passive Infra Red) movement sensor module, which as the name infers utilized for recognizing the movement of a body before it. The gadget works dependent on infrared innovation and it would automatic be able to control without anyone else's input with high affectability and high unwavering quality. As a result of the base estimate and low-power activity mode, it broadly utilized in battery-fueled applications.
