como hacer funcionar un sensor de ultrasonido y un sensor de temperatura

-

buenas estoy realizando un proyecto de un ventilador que funcione con sensor de temperatura y sensor ultrasonido. el ventilador tiene que encender si encuentra algún movimiento siempre y cuando este una temperatura mayor de 20°c, y si no hay esa temperatura no debe prender, ya probé mis dos sensores pero ahora no se como unir los dos y que me funcione el ventilador, que códigos uso para el arduino.
muchas gracias.

we don't code here... going, study bit , propose electrical set , associated code , provide input

you need relay on top of sensors drive fan (assuming it's big fan room)

alternatively buy wired home automation kit , use "if that" type of ide comes those

hey everyone, i'm trying compile simple code on rpi3 using geany. code written using code::blocks on windows , working without problem. errors i'm getting are: untitled.c:33:5: error: ‘for’ loop initial declarations allowed in c99 or c11 mode , untitled.c:33:5: note: use option -std=c99, -std=gnu99, -std=c11 or -std=gnu11 compile code understand code not problem way i'm compiling it. can give me advice? you need add 1 of suggested options compile command configured in geany, in menu.. build -> set build commands add "-std=c99" after "gcc" in compile , build boxes. (i'm looking on mint pc expect version on pi same). petero raspberrypi
