It contains specifications and setup information for S-node and S-node modular gateways. Follow this manual exactly for a complete setup. 2 INTRODUCTION 2.1 Product Overview (S-Node) S-node is a tiny, truly plug-and-play sensor node designed to enable predictive maintenance at a fingertip. S-node is able to measure 3D vibration, accostic emissions, gas emissions, RPM and IR thermal. S-node send data to the S-node modular gateway by using RF 2.4 GHz and Gateway send that data to the S-node cloud using MQTT protocol. A Highly scalable hardware architecture allows for plugging the sensors on a node as per the industrial requirement. Later on, machine learning algorithms will process data to estimate machine downtime and generate real-time notifications in the event of any unexpected situations, which will appear on the dashboard of the S-node.

The gain of the antennas used in the product is extracted from the Antenna data sheets provided and also the maximum total power input to the antenna is measured. Through the Friis transmission formula and the maximum gain of the antenna, we can calculate the distance, away from the product, where the limit of MPE is reached. Although the Friis Transmission formula is far field assumption, the calculated result of that is an over-prediction for near field power density. It is taken as worst case to specify the safety range. 1.2 RF Exposure Limit According to FCC 1.1310: The criteria listed in the following table shall be used to evaluate the environmental impact of the human exposure to radio-frequency (RF) radiation as specified in 1.1307 (b) showed in Table 1. Table 1: Limits for Maximum Permissible Exposure (MPE) as per FCC Frequency Range (MHz) Electric Field Strength (V/m) Magnetic Field Strength (A/m) Power Density (mW/cm²) Limits for Occupational / controlled Exposures 300 - 1500 -- -- F/300 1500 – 100000 -- -- 5.0 Limits for General population / Uncontrolled Exposure 300 - 1500 -- -- F/1500 1500 – 100000 -- -- 1.0 F or ƒ = Frequency in MHz 1.2.1 Friss Formula Friss Transmission Formula: Pd = (Pout * G) / (4*pi*r²) Where Pd = power density in mW/cm² Pout = output power to antenna in mW G = gain of antenna in linear scale Pi = 3.1416 R = Distance between observation point and the center of radiator in cm If we know the maximum gain of the antenna and the total output power to the antenna, through calculation, we will know MPE value at distance 20cm.

It is preferable to use a shunt capacitor since a capacitor is cheaper than an inductor and because a shunt compone nt can be removed without any impact. +91 8591900346 When the length of the antenna is adjusted, it is important to completely remove the piece of track that is cut off since any remaining metal affects the antenna. Figure 4: Impedance after length adjustment. After the length is adjusted, and the impedance is getting close to the conductance circle that passes through the centre of the Smith chart, see Figure 4, a suitable capacitor is used to bring the impedance to the 50 ohm point, see Figure 5. In this case, a 1.0 pF capacitor gives the best results. The exact value can be calculated, or it can be found by trial and error. +91 8591900346 Figure: 5 Impedance after length adjustment and adding a shunt capacitor.
