8. DS18B20 (Digital Temperature Sensor) and Arduino

One of the most straightforward and economical ways to include temperature detecting in your Arduino extend is to utilize a DS18B201 – Wire Temperature Sensor. These sensors are reasonably exact and need no outside components to work. So, with a fair number of connections and a few Arduino codes you’ll be detecting temperature in no time! 

Hurrah! you don’t have to Google now.

The sensor comes ordinarily in two shape components. One that comes in a TO-92 bundle looks precisely like a conventional transistor. Another one in a waterproof test fashion can be more valuable after you need to measure something distant, absent, submerged, or beneath the ground.

The DS18B20 temperature sensor is reasonably exact and needs no outside components to work. It can measure temperatures from -55°C to +125°C with ±0.5°C Accuracy. Be that as it may, the default determination at power-up is 12-bit. The sensor can be powered with a 3V to 5.5V control supply and consumes as little as 1mA amid dynamic temperature transformations.

What components do you need for DS18B20 (Digital Temperature Sensor) and Arduino?

Here’s the list of components required for making digital computer sensor

  • Arduino UNO
  • Maxim integrated DS18B20 programmable resolution 1-wire digital thermometer.
  • Resistor 4.75k ohm
  • Breadboard band

9. Smoke detection using MQ-2 gas sensor

This Arduino project has a nose for gasses with the MQ2 Gas Sensor Module. This can be a strong Gas sensor reasonable for detecting LPG, Smoke, Liquor, Propane, and Hydrogen concentrations within the air. In the event that you’re arranging on making an indoor air quality monitoring system; breath checker or early fire discovery framework, MQ2 Gas Sensor Module could be an incredible choice.

MQ2 is one of the commonly utilized gas sensors in the MQ sensor series. It could be a Metal Oxide Semiconductor (MOS) sort Gas Sensor moreover known as Chemiresistors as the discovery is based upon altering of resistance of the detecting material when the Gas comes in contact with the material. Employing a basic voltage divider, concentrations of the gas can be identified.

The MQ2 Gas sensor will work on 5V DC and use around 800mW. It can detect LPG, Smoke, Liquor, Propane, Hydrogen, Methane, and Carbon Monoxide concentrations anywhere from 200 to 10000ppm.

How Smoke Detection works?

The voltage that the sensor outputs changes appropriately to the smoke/gas level that exists within the climate. The sensor outputs a voltage that’s corresponding to the concentration of smoke/gas.

In other words, the relationship between voltage and gas concentration is the following:

The greater the gas concentration, the greater the yield voltage. The lower the gas concentration, the lower the yield voltage. Within the presence of decreasing gasses, the surface thickness of adsorbed oxygen decreases because it responds with the decreasing gasses. Electrons are at that point discharged into the tin dioxide, permitting current to stream openly through the sensor.

What components do you need for Smoke detection using the MQ-2 gas sensor?

The below listed components needed to make this smoke detection project

  • Arduino UNO
  • Breadboard
  • MQ-2 Smoke detection sensor
  • Male/Female jumper wires
  • 5mm LED Red
  • 5mm LED Green
  • Buzzer
