    hc-sr04 and raspberry pi

    Yes you are right.. You can connect the 3.3V output of raspberry pi directly to ECHO input of HC-SR04.... It will detect 3.3V as HIGH level... as TTL logic... but the 5V TRIGGER output of HC-SR04 should not be directly connected to 3.3V input of Raspberry Pi.. it may damage it.. You should use...
