Introduction

Currently, nanomaterials are widely used in all fields of activity. They have unique properties due to small size, structure, chemical composition and large surface area. This article examines the use of electronic sensors based on nanomaterials. Manometer-instrument for measuring of excess pressure in liquid and gaseous media. Manometric devices have a variety of applications: industry, transport, household appliances, scientific researches etc.

Methods

The main method of obtaining the CNM was the CVD method. This method is relevant, in connection with the frequency of output. The essence of the method is the pyrolytic decomposition of a gas containing carbon and the synthesis of CNTs on catalyst particles that are in the form of a thin film on a substrate or a powder in a stationary or mobile (pseudo-boiling) layer.

Results

Initially, Si substrates were used which were previously deposited by spraying the film with Ni catalysts, for the further growth of CNTs. The process of synthesis, growth of CNTs passed in a tube furnace with a gradual heating up to 750⁰ C, and also with a constant supply of hydrogen. After the temperature of the preset bar 750⁰ C was set, the alcohol itself was supplied directly for 15-20 minutes, the carbon carrier, which when decomposed into the oven and deposited on the film, formed CNTs with Ni catalysts on the film, the average tube diameter reached 80 nm, and the structure was a felt of a long order of 1.5 μm.

Discussion

In this work, an experiment was carried out with Ni catalysts at a temperature of 750 ° C for 15-20 min, and CNTs with a diameter of 80 nm were formed on the film, and the structure was 1.5 μm. The resulting nanotubes were used in manometers with a possible remote control system. Next, a hardware part was created that was a set of mounted PCBs and a software part with output to wireless interfaces. The wireless electronic manometer reduces operational costs, improves security and provides continuous access to data through a wireless device via Bluetooth or Wi-Fi.
