Arduino controlled relays mounted on DIN-rail

-

hi

i'm looking solution can use arduino (mega) control relays . requirements are
- 240vac
- din rail mounted
- 1 or more relays in single module
- may require external power (to avoid buring arduino pins) not external elements wire (e.g. transistors)


i did research , found lot of 12v relays need input power control relay state.

could recommend solution? perhaps share links existing products in online shops (ideally worldwide delivery)

maybe instead of looking 5v relays there shields changes 5v 12v?

mirek

in general arduino cannot provide enough current trigger coil in electro-mechanical relay if has 5v coil. need transistor between arduino , coil.

you can buy small board-mounted relays use arduinos have necessary transistors included. maybe similar available din rail mounting. suspect of relays controlled plcs able drive regular relays.

the other option solid-state relay has ttl input.

...r

i'm struggling dht11 sensor work on arduino. code compiles without problems in serial monitor output keep on getting " read sensor: time out error" i've tried multiple libraries, adafruit etc still none of them worked. set serial monitor same speed (115200) didn't fix problem.  i'm using:  mega2560  dht11 temp+hum sensor windows10 x64 arduino 1.6.9 library dht11.h v0.4.1 source:  http://playground.arduino.cc/main/dht11lib wiring : blue = gnd yellow = 2 red = 5v (also see picture)  my code:    code: [select] #include <dht11.h> // //   file:  dht11_test1.pde // purpose: dht11 library test sketch arduino // //celsius fahrenheit conversion double fahrenheit(double celsius) {   return 1.8 * celsius + 32; } // fast integer version rounding //int celcius2fahrenheit(int celcius) //{ //  return (celsius * 18 + 5)/10 + 32; //} //celsius kelvin conversion double kelvin(double celsius) {   return ...

Arduino Uno + KTY81/210 temperature sensor

hi, sorry, new , unsure lot of things, need clarification. haven't found information explains how , why things work, "do this, that" i following guide ( arduino-thermistor-temperature-sensor-tutorial ) connect thermistor arduino uno. here temperature sensor information: temp. sensor 2000r +-1% to92 part.no.:   kty81-210 name:   temp. sensor 2000r +-1% to92 description:   2.5mm, 1980...2020ohm, -55...+150°c and here sensor's data-sheet: sensor data-sheet i have connected same way in guide. works , values being serial printed. what don't understand: 1. thermistor's , resistor's ohm value should equal, correct? in case 2000 ohm? 2. thermistor has ptc, i'm guessing have invert math or use ntc thermistor instead correct values? (currently resistance goes temperature goes down) 3. understand code uses steinhart-hart math logic convert resistor value temperature value, need a, b , c coefficients of thermis...
