in indicators, u have --> Ethernet Link - Green – Ethernet Link. if u can open this serial converter, take wires from that LED and connect to a detector device. this device can reset the device by turning on the relay when there is a power failure.
if u cant open the converter, use a LDR to...
does the device has any indication for internet connectivity? like LED to show TCP/IP connection ?? if u have any datasheet or web link reg the device send it
so its the problem with the tubelight and its choke... if this happens oly with that particular light, i would suggest you not u use it. it may cause interferance with nearby devices too.
To restart the device you must design an embedded device that continuously monitors the internet connection and if there is any problem with the internet connection, it must send a trigger pulse to reset your devise.
I guess there must be a reset button in your device, if so u can connect a...
Well i had similar problem, while controlling a motor the controller gets hanged. This must be because of EM interference. the choke coil of a tub light T5 is designed with a high turns coil. hence is may produce high EM during the start. this can be coupled with the circuit of your arduino or...
Hello,
I am working on a project that needs to automatically stop 3 phase motor, through a DOL starter. The signal from the controller is given to a relay to stop the motor. A NC relay in series with the starter coil will do the job. but im not sure of the rating of the relay to be used...
simple way is to decide the value of the capacitor by a simple calculation. note down the switching time between the grid and UPS source, i.e. the time when the power goes off and the UPS starts delivering power. this time interval must be compensated by a capacitor, supplying the power. measure...
I just connect a switch between trigger input and GND. so thats the only input !! i guess its the noise from AC .... i dono what to do to solve this...
i would suggest labview and daq ... as it can also be used to process the data that u acquire , if needed. and working with GUI bases programming is much simpler !!....
I tried the VI ... the program works very fine... i don't get any error. But i have tried my manually entering the string, but how did u interface the temp value obtained with the TCP/IP program??
From the datasheet of the Transceiver, Pin 4 and 5 are used for USART communication. Thery are TTL compatible, i.e. works with digital 5v. Hence the Tx and Rx of the module can be connect directly to the Rx and Tx pins of the Arduino (digital 1 & 0 pins). the module can be powered from the...
