Timer programming for 8051 using embedded cVikas Dongre
The document discusses the timers and counters of the 8051 microcontroller. It describes that the 8051 has two 16-bit timers/counters that can be used as timers to generate delays or as event counters. These timers are accessed as two 8-bit registers - a low byte register (TL0/TL1) and high byte register (TH0/TH1). It also explains the timer mode register TMOD and provides code examples to use the timers for generating delays and frequencies.
The Intel 8086 is a 16-bit microprocessor that can access up to 1 MB of memory. It has two main components: the Bus Interface Unit (BIU) handles bus operations like instruction fetching and memory access, while the Execution Unit (EU) decodes and executes instructions. The BIU contains registers for the code, data, extra, and stack segments as well as an instruction queue. The EU has registers for accumulation, base, count, data, pointers, and flags, and contains an ALU and decoder. It executes instructions from the queued bytes using a pipeline architecture.
There are three types of counter function blocks used in PLC programming: 1) Up counters that count each event and set the output when reaching the limit, 2) Down counters that count down from a limit to zero and set the output, and 3) Up-down counters that can count in both directions and set two outputs depending on reaching the limits. Each type has inputs to count, reset, and load the counter value and an output triggered at the limit. Exercises are provided to write LAD programs demonstrating each counter type.
The main purpose of the project is to detect the location of fault in underground cable lines from the base station in kilometers using a Renesas micro-controller. This project uses the standard concept of Ohms law i.e., when a low DC voltage is applied at the feeder end through a series resistor to the Cable lines, then current would vary depending upon the location of fault in the short circuited cable. Both the methods use voltage convertor, microcontroller and potentiometer to find the fault location under unsymmetrical faults.
In the urban areas, the electrical cables run in undergrounds instead of overhead lines. Whenever the fault occurs in underground cable it is difficult to detect the exact location of the fault for process of repairing that particular cable and long outage of power supply can cause the power distributors and retailers heavy loss of revenue and discomfort of the customers. Therefore, a quick detection and rectification of the faults is a major drawback for other power distributors and retailers. The proposed system finds the exact location of the fault using GSM Module and IOT
This system uses a Renesas micro-controller and a rectified power supply. Here the current sensing circuits made with combination of resistors are interfaced to Renesas controller with help of the ADC device for providing digital data to the microcontroller representing the cable length in KM’s. The fault creation is made by the set of switches. The relays are controlled by the relay driver IC which is used for switching the power sequentially to all the lines. A 16x2 LCD display connected to the microcontroller to display the information.
In case of short circuit (Line to Ground), the voltage across series resistors changes accordingly, which is then fed to an ADC to develop precise digital data to a programmed Renesas board that further displays fault location in kilometers.
The project future can be implemented by using capacitor in an ac circuit to measure the impedance which can even locate the open circuited cable.

Newly poured concrete opposing hot and windy conditions is considerably susceptible to plastic shrinkage cracking. Crack-free concrete structures are essential in ensuring high level of durability and functionality as cracks allow harmful instances or water to penetrate in the concrete resulting in structural damages, e.g. reinforcement corrosion or pressure application on the crack sides due to water freezing effect. Among other factors influencing plastic shrinkage, an important one is the concrete surface humidity evaporation rate. The evaporation rate is currently calculated in practice by using a quite complex Nomograph, a process rather tedious, time consuming and prone to inaccuracies. In response to such limitations, three analytical models for estimating the evaporation rate are developed and evaluated in this paper on the basis of the ACI 305R-10 Nomograph for “Hot Weather Concreting”. In this direction, several methods and techniques are employed including curve fitting via Genetic Algorithm optimization and Artificial Neural Networks techniques. The models are developed and tested upon datasets from two different countries and compared to the results of a previous similar study. The outcomes of this study indicate that such models can effectively re-develop the Nomograph output and estimate the concrete evaporation rate with high accuracy compared to typical curve-fitting statistical models or models from the literature. Among the proposed methods, the optimization via Genetic Algorithms, individually applied at each estimation process step, provides the best fitting result.

Welcome to the May 2025 edition of WIPAC Monthly celebrating the 14th anniversary of the WIPAC Group and WIPAC monthly.
In this edition along with the usual news from around the industry we have three great articles for your contemplation
Firstly from Michael Dooley we have a feature article about ammonia ion selective electrodes and their online applications
Secondly we have an article from myself which highlights the increasing amount of wastewater monitoring and asks "what is the overall" strategy or are we installing monitoring for the sake of monitoring
Lastly we have an article on data as a service for resilient utility operations and how it can be used effectively.
Citizen Observatories (COs) are innovative mechanisms to engage citizens in monitoring and addressing environmental and societal challenges. However, their effectiveness hinges on seamless data crowdsourcing, high-quality data analysis, and impactful data-driven decision-making. This paper validates how the GREENGAGE project enables and encourages the accomplishment of the Citizen Science Loop within COs, showcasing how its digital infrastructure and knowledge assets facilitate the co-production of thematic co-explorations. By systematically structuring the Citizen Science Loop—from problem identification to impact assessment—we demonstrate how GREENGAGE enhances data collection, analysis, and evidence exposition. For that, this paper illustrates how the GREENGAGE approach and associated technologies have been successfully applied at a university campus to conduct an air quality and public space suitability thematic co-exploration.
