•We introduce the first ever pipeline for sound classification using Deep Learning in extremely resource-constrained (battery-powered, low memory and CPU speed) microcontrollers (MCUs).•Firstly, we ...present a CNN architecture (ACDNet) that achieves state-of-the-art classification accuracy for raw audio classification on ESC-10, ESC-50, UrbanSound8K and AudioEvent benchmark datasets.•Secondly, we compress ACDNet using our proposed hybrid structured compression technique to obtain Micro-ACDNet that is 97.22% smaller in size and requires 97.28% fewer FLOPs yet produces close to state-of-the-art performance.•Finally, after 8-bit quantization, we deploy Micro-ACDNet on a standard off-the shelf MCU.
Significant efforts are being invested to bring state-of-the-art classification and recognition to edge devices with extreme resource constraints (memory, speed, and lack of GPU support). Here, we demonstrate the first deep network for acoustic recognition that is small, flexible and compression-friendly yet achieves state-of-the-art performance for raw audio classification. Rather than handcrafting a once-off solution, we present a generic pipeline that automatically converts a large deep convolutional network via compression and quantization into a network for resource-impoverished edge devices. After introducing ACDNet, which produces above state-of-the-art accuracy on ESC-10 (96.65%), ESC-50 (87.10%), UrbanSound8K (84.45%) and AudioEvent (92.57%), we describe the compression pipeline and show that it allows us to achieve 97.22% size reduction and 97.28% FLOP reduction while maintaining close to state-of-the-art accuracy 96.25%, 83.65%, 78.27% and 89.69% on these datasets. We describe a successful implementation on a standard off-the-shelf microcontroller and, beyond laboratory benchmarks, report successful tests on real-world datasets.

One common method of harnessing solar energy is via a Photovoltaic (PV) system. When sunlight strikes a PV panel surface at around ninety-degree angle, the system produces the most energy. The ...electricity generated by a PV system may be increased by using a solar tracker (ST). However, the ST has its own energy requirements and additional expenses. A semi-continuous single-axis ST is developed for this purpose. The “Semi-continuous tracking algorithm ” is used to monitor the sun rather than constant tracking in the developed ST. While comparing the performance of a fixed PV system, a continuous single-axis solar tracker-based PV system, and a semi-continuous single-axis solar tracker-based PV system, the developed semi-continuous system is only slightly less efficient than the continuous system (by 1.12 %). Nevertheless compared to a PV system with continuous tracking, the semi-continuous tracking system reduces self-energy consumption by 34%.
•Introduction of a novel algorithmic approach of semi-continuous tracking system for a single axis solar tracker.•This system enhance the collection of solar radiation along with reducing self power consumption resulting in a higher output power of the PV system.•A delay duration of 4 min was used in tracking period of this algorithm.•The energy usage of a semi-continuous solar tracker system is found notably lower, about 34 %, compared to a continuous tracking system due to the inactivity of the solar tracking modules during the delay period.

A Bluetooth based battery-powered remote-controlled direct rice seeder was developed to overcome the drudgery and operational difficulties involved in direct seeding by manual drum seeder. The ...developed seeder consists of micro-controller unit, stepper motor, DC geared motor, motor drivers, battery, wheels and frame. The micro-controller unit is the heart of the developed mechatronic system. The micro-controller unit was designed and developed by Programming. A mobile application was designed and developed to connect the seeder to mobile through Bluetooth connectivity and operated range of 47.6 m which is sufficient for hilly region topography. The developed seeder was evaluated in laboratory conditions at different forward speeds varying from 0.5 to 3.0 km.h−1 and hopper fill levels varying from 25% to 75%. Forward speed of 0.7 km.h−1 and 75% hopper fill level were found optimum with corresponding seed rate of 20.2 kg. ha−1, missing hill index of 0%, hill spacing uniformity of 93.7%, coefficient of variance of number of seeds per hill of 0.25 and hill span of 9.4 cm. The developed seeder was evaluated in the field in puddled soil conditions in Sajong village, East Sikkim, India and the performance was compared with manual drum seeder. The field capacity and field efficiency of the developed seeder was found to be 0.017 ha.h−1 and 62% respectively as compared to 0.023 ha.h−1and 82% in case of manual drum seeder respectively. The developed seeder has reduced drudgery/cumbersome of 64% over manual drum seeder as evident from operator's heart rate and energy expenditure rate. In addition to that the operator can able to sit in a safe and comfortable environment outside the field to operate the developed drum seeder. Moreover, the developed seeder reduces the operational cost of 230 ₹. ha−1 over manual drum seeder.

Loess–mudstone/soil-rock interfacial landslide is one of the prominent landslide hazards that occurs in soil rock contacting zones. It is necessary to develop sensors with high sensitivity to weak ...and low frequency vibrations for the early warning of such interfacial landslides. In this paper, a novel monitoring sensor prototype with enhanced and adaptive sensitivity is developed for this purpose. The novelty of the sensitive sensor is based on the variable capacitances and negative stiffness mechanism due to the electric filed forces on the vibrating plate. Owing to the feedback control of adjustable electrostatic field by an embedded micro controller, the sensor has adaptive amplification characteristics with high sensitivity to weak and low frequency input and low sensitivity to high input. The design and manufacture of the proposed sensor prototype by Micro-Electro-Mechanical Systems (MEMS) with proper packaging are introduced. Post-signal processing is also presented. Some preliminary testing of the prototype and experimental monitoring of sand interfacial slide which mimics soil–rock interfacial landslide were performed to demonstrate the performance of the developed sensor prototype with adaptive amplification and enhanced sensitivity.
