This module produces an digital output based on the humidity of the local environment. Whether it be a Weather station, greenhouse monitor or other project you will be able to trigger devices when a certain amount of water is in the air.
As a standard module for humidity detection, Arduino development does not require a library but instead readings can be read from the output pin. Simply on reaching the set threshold the output will be driven LOW. This opens up the opportunity for an interrupt based program to cut down on power consumption while waiting to hit the threshold.
Berikut contoh penggunaan HR202 bersamaan dengan Arduino UNO, ambil tegangan 5V dan Ground dari Arduino, kemudian data (output) dari sensor dipasang di A0 (pin analog Arduino). Download Script.
Data hasil pembacaan dari script diatas dapat kita pantau dari menu Serial Monitor di Sfotware Arduino (Tools > Serial Monitor). Contoh hasil pembacaannya sebagai berikut :
Jika kita menghendaki data original (data analog) keluaran dari modul maka dapat gunakan script Arduino pembacaan data analog sbb. Download Script.
