hi ppl hows it goin.. i had a look on google and the forums but was havin trouble finding d info i was after...
basically, i want to transmit an ultrasonic signal, through air. i was wondering what the maximum range/power i can get on these things? obviously i dont want the device to be too big.. the smaller the better, as small as possible to be honest...but yes i was wondering on the greatest range i can get and what type of power consumption it would need for that range approximately. im hoping for max 100m range .... minimum.. 25m range... but a 50m range would be ideal... is this possible do u think and if u know of any device that can produce this thats online and u kno where i could find it could u let me know please... i would also like it to be omnidirectional if possible.
i was also wondering how penetrative this signal at high power can be, for example, if it was to be transmitted inside a greenhouse... could it get through the walls and be able to potentially reach 50m range?
iv been having a look around but i cant find specific info on this..
i dont need to kno exactly but if anyone knows if this is feasable or approx max range i can get an wot penetration/power consumption/cost wud b like for the ideal range of 50m etc i would appreciate it a lot.
thanks
