MQ-4 (Methane Gas Sensor module for Arduino)
₨ 280.00 ₨ 220.00
Gas sensor MQ4 registers presence and concentration of natural gas and methane (CH4). The best results are given when gas is in liquid form, however, since situations like this are rare, it does its job pretty well when in gas form, too. It needs a bit of time to warm up in order to work correctly.

DHT22- (Temperature and humidity sensor)
Product description:
The DHT22 module is designed to measure the temperature and humidity of the atmosphere. The difference from the younger model (DHT11), The DHT22 has a wide range and a high precision determination of temperature and humidity. The sensor works on the OneWire bus, which makes it possible to connect it to the Arduino only three wires ( two of which are POwer supply). Low power consumption allows you to install it on stand-alone devices.
