data acquisition and control system - Мозилин фајерфокс (Mozilla Firefox) In this section, we will discuss the practicle issues og ADC0804 and Signal control on ADC0804. Then we will move to the interfacing of ADC0804 with microcontroller. Signal control on ADC0804 1. Note: CS is set to low for both RD and WR pulses. Write a program to monitor the INTR pin and bring the digital input value into register A. Example of ADC Application Temperature detection A temperature sensor (LM34 or LM35) is interfaced to the 8051 via an ADC (ADC0804) The output voltage from the LM34/LM35 is linearly proportional to the measuring temperature The ADC0804 converts the output voltages from the LM34/LM35 into digital signals, which correspond to the measured temperature.They are then handled by the 8051 Interfacing with the LM35 (Temperature Sensor) ADC Application:- The ADC0804 converts the output voltages from the LM35 into digital signals, which correspond to the measured temperature.

Groupe surpresseur: Surpresseur d'eau de pluie Pour acheminer l'eau d'une cuve à eaux de pluie ou d'un puits vers les points de consommation, il est nécessaire d'avoir un groupe surpresseur dont les éléments principaux sont la pompe, le contact manométrique et le vase d'expansion. groupe supresseur : Obtenez gratuitement des devis ! Pour acheminer l'eau d'une cuve à eaux de pluie ou d'un puits vers les points de consommation, il est nécessaire d'avoir un groupe surpresseur dont les éléments principaux sont la pompe, le contact manométrique et le vase d'expansion. Cet article décrit la plomberie nécessaire et la méthode détaillée pour réaliser ce groupe surpresseur. Composition du groupe surpresseur Le vase d'expansion est un réservoir contenant une vessie d'air sous pression qui permet d'assurer un "tampon de pression" servant à diminuer le nombre d'arrêts/redémarages de la pompe. Procédure Zoom Pour étanchéifier les raccords à visser, la méthode la plus simple est d'utiliser un rouleau de téflon (ci-contre). Zoom Zoom Zoom Zoom 1. Zoom Zoom
Frequency counter with PIC and 4- to 5-digit LED display This document describes the construction of small frequency counter with a cheap PIC microcontroller and a few seven-segment LED digits. The main features of the frequency counter are: frequency range 1 Hz ... 50 MHz (prototype worked up to 60 MHz but this exceeds the PIC's timing specifications) four or five digits resolution (display for example x.xxx kHz, x.xxx MHz, or xx.xx MHz); or 6 digits with F8FII's modification automatic range switching with different gate times optional addition or subtraction of a frequency offset (programmable) optional preamplifier for the input signal can be built on a single-sided 'breadboard-style' circuit board firmware available for common-cathode as well as commom-anode displays very low component count: a PIC 16F628, 4 or 5 7-segment LED displays, a 4- or 20-MHz crystal and a few resistors, optionally one transistor and a few diodes to drive the 5th digit, optionally one other transistor for the preamplifier.

Choose either a fully assembled product, or a DIY kit (including PCB, components, and enclosure to make your own OpenSprinkler). Mobile Web App Tutorial Firmware 1.8 Video Tutorial Updates OpenSprinkler new mobile app (native version) is now available on all platforms. Overview OpenSprinkler is an open-source Internet / web-based sprinkler timer / controller built upon the Arduino platform. Basic Feature List: Built-in Ethernet controller provides web-based scheduling and monitoring, through either wired or WiFi connection (note: WiFi connection requires a wireless adapter or bridge).Based on ATMEL microcontroller and the open-source Arduino software. Differences with Similar Products: Web-based sprinkler timer is not a new idea. OpenSprinkler’s built-in microcontroller runs water schedules on its own.

cheap-thermocam.tk A watering controller that can be home networked A couple of weeks ago, I published a great little controller module that provided 6 relays able to be controlled from a computer via a network. After I published it, I got to thinking that the same basic design, with a couple of changes could be pressed into service as a garden watering system controller. So, I got to work, modified the design, and here you have it... This specific version of my sprinkler controller obeys some simple rules that have had to be implemented where I live. This system, along with the mandatory replacement of sprinklers for dripper systems has sucesfully reduced the load on the cities limited inland water supply so that more drastic measures were not required. Unfortunately, this system was unable to be implemented on my commercial water controller, it wanted to water on a Monday, or a Wednesday, so I was breaking the law, and subjecting myself to a potential fine every other week...

FT232R is the latest device to be added to FTDI’s range of USB UART interface Integrated Circuit Devices. The FT232R is a USB to serial UART interface with optional clock generator output, and the new FTDIChip-ID™ security dongle feature. In addition, asynchronous and synchronous bit bang interface modes are available. USB to serial designs using the FT232R have been further simplified by fully integrating the external EEPROM, clock circuit and USB resistors onto the device. The FT232R adds two new functions compared with its predecessors, effectively making it a "3-in-1" chip for some application areas. The internally generated clock (6MHz, 12MHz, 24MHz, and 48MHz) can be brought out of the device and used to drive a microcontroller or external logic. The FT232R is available in Pb-free (RoHS compliant) compact 28-Lead SSOP and QFN-32 packages. Press releases, articles and web links related to the FT232R can be found here.
