Drosophila Environment Monitor（果蠅環(huán)境監(jiān)視器）
環(huán)境監(jiān)視器持續(xù)測量周圍空氣的濕度和溫度，以及監(jiān)測監(jiān)視器表面光的亮度。在整個實驗過程中，這些參數(shù)被持續(xù)測量，并定時上傳到電腦，作為培養(yǎng)器皿的一種環(huán)境數(shù)據(jù)。
溫度和濕度由安裝在環(huán)境監(jiān)視器頂部的精密的傳感器所檢測，頂部和底部都開有多個小孔，利于空氣流通和監(jiān)測。
光的強度由安裝在頂部表面的一個光電二極管傳感器檢測，一個濾光片將會把紅外光和紫外光濾掉，使得能夠準確的測量適應(yīng)光的強度。
在整個測量期間，每個瞬時值都會被記錄下來，包括zui小值、平均值和zui大值，提供瞬時和長時程的環(huán)境的參數(shù)。
