“…The absorption spectrum shown in Figure 1D reveals a sharp absorption edge at~340 nm related to the direct band edge transition of SnO 2 . 18,25,26 Here, the strong electrostatic field, generated due to presence of oxygen vacancies 27,28 (existence of oxygen vacancies were confirmed with photoluminescence spectra shown in Figure S1), dissociates the water molecules (as seen in Figure 2B) according to Tauc plot, as shown in the inset of Figure 1D, confirms a direct bandgap of~3.62 eV and is in accordance with earlier report.…”

“…[22][23][24] The water surrounding the pallet generates pressure, which also helps the water molecules to penetrate inside the pores. 18,25,26 Here, the strong electrostatic field, generated due to presence of oxygen vacancies 27,28 (existence of oxygen vacancies were confirmed with photoluminescence spectra shown in Figure S1), dissociates the water molecules (as seen in Figure 2B) according to…”

“…The temperature sensor, humidity sensor [10,11] and smoke sensor installed in the robot can collect the environmental parameters and send data to the server by STM32 and MQTT protocol [12,13]. In order to make users more convenient to observe the environmental parameters, in the process of receiving data, the same way of receiving data is used.…”

“…These advantages benefit this type of sensor with a wide range of industries [43]. The piezo-optic sensors are the systems that use optical fiber technology to transport a light input signal that is modulated according to a measured object magnitude and then collected by a detector, conditioned, and processed [44].
