AHT20 I2C temperature and humidity sensor High Precision Digital module Price in electronicstore.pk

Sensitive material of MQ-7 gas sensor is SnO2, which with lower conductivity in clean air. It make detection by method of cycle high and low temperature, and detect CO when low temperature (heated by 1.5V). Electronicstor.pk

MQ8 MQ 8 MQ-8 Hydrogen Gas Sensor Module H2 Alarm Detection MQ-8 Sensor Hydrogen Gas Sensor Module H2 Alarm Detection use in clean air low conductivity tin oxide (SnO2). When there is the environment in which the combustible gas sensor, conductivity sensor with increasing concentration of combustible gases in air increases. Using a simple circuit to convert the change in conductivity of the gas concentration corresponding to the output signal. MQ-8 hydrogen gas sensor of high sensitivity, the monitoring of the other hydrogen-containing gas is also very satisfactory. This sensor can detect a wide range of hydrogen gas, city gas, in particular, is a low-cost sensor for a variety of applications.

RS485 to TTL / TTL to RS485 converter is a module that allows the TTL interface of the microcontroller to be transferred to the RS485 module / MAX485 module. It is generally used for industrial automation. This module adds lightning protection design and anti-jamming design. When we use it in the field and carry out long distance transmission, we can Connect the GND end of the module to the ground so that lightning protection and anti-interference can be achieved. This Max485 to TTL module is online in Pakistan
