This work involves developing a Bluetooth-controlled fire extinguisher vehicle using the ESP32 microcontroller, enhanced with a gas sensor for safety and autonomous operation. The vehicle is remotely controlled via a mobile device, thanks to the ESP32's Bluetooth functionality, allowing precise navigation and fire suppression. The ESP32 serves as the system's core, working alongside an L293D Motor Driver Shield, a fire sensor, and a water pump to control both movement and fireextinguishing actions. A 3.3-5V submersible water pump with a 20cm pipe activates when fire is detected. In autonomous

Abstract:

As the information collection device of the current domestic down-hole gathers less information and with low precision, the down-hole monitoring system with multi-parameter is designed in this paper. The system can be used on electric submersible pump to achieve two-way pressure, two-way temperature, leakage current, and vibration signals in real-time acquisition. Filtering the collected data, and using curve fitting algorithm on the pressure sensor for temperature compensation to ensure the accuracy of the data. Test results show that the system can withstand the harsh down-hole environments

The paper deals with the pressure fields in a water well during its cleaning from salt deposits using electric discharge equipment with the location of the charging and discharging device on the Earth surface. The curves of the spatial pressure distribution in a water well were obtained. Those graphs could be used to determine the processing modes, namely the number of processing points per 1 linear meter of the well. The results obtained showed a strong influence on the cleaning efficiency of the parameters of the high-voltage cable that connects the surface and submersible parts (electrical

Abstract:

Transient based technique is known as one of the most economical ways for pipeline condition assessment. This technique involves monitoring and analysing pressure transient profiles at multiple points in a distributed system. Its application is restricted due to its low spatial resolution (10 m). It is hypothesised that by increasing the number of pressure transducers and reducing the gauge length (distance between the transducers), the spatial resolution of the measurements would highly be improved. However, the deployment of pressure transducers is restricted to the location of the hydrants.

A submersible device was constructed for simultaneous in situ measurement of the effective quantum yield of chlorophyll fluorescence (ΔF / Fm′) of eight macroalgal samples. The device incorporated a commercially available PAM fluorometer. Four samples each of the macroalgae Iridaea mawsonii (Lucas) and Monostroma hariotii (Gain) were examined. ΔF / Fm′ and light-response curves (LCs) were regularly applied over 24 h to estimate diel changes in relative electron transport rates and the relative efficiency of photon conversion at low irradiances (α), and the variance attributable to mean values
