Drosophila Environment Monitor（果蠅環(huán)境監(jiān)視器）
環(huán)境監(jiān)視器持續(xù)測(cè)量周圍空氣的濕度和溫度，以及監(jiān)測(cè)監(jiān)視器表面光的亮度。在整個(gè)實(shí)驗(yàn)過(guò)程中，這些參數(shù)被持續(xù)測(cè)量，并定時(shí)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(cè)，頂部和底部都開(kāi)有多個(gè)小孔，利于空氣流通和監(jiān)測(cè)。
光的強(qiáng)度由安裝在頂部表面的一個(gè)光電二極管傳感器檢測(cè)，一個(gè)濾光片將會(huì)把紅外光和紫外光濾掉，使得能夠準(zhǔn)確的測(cè)量適應(yīng)光的強(qiáng)度。
在整個(gè)測(cè)量期間，每個(gè)瞬時(shí)值都會(huì)被記錄下來(lái)，包括zui小值、平均值和zui大值，提供瞬時(shí)和長(zhǎng)時(shí)程的環(huán)境的參數(shù)。

Features
• Accuray measures temperature, relative
humidity, and incident ambient light.
• Precision temperature measurement verifies
incubator setpoint accuracy and stability.
• Ambient light sensor verifies proper on/off
light cycling, and detects inadvertent door
openings, confirming true-dark conditions.
• Accurate lux measurement checks lighting
intensity and uniformity.
• Min/Max readings detect short-term upsets to
average conditions.
• Small unit size allows parameter measurement
at various points within a chamber interior.
• ephone-type wiring jack allows easy
connection to DAMSystem wiring network.
• Data acquisition via standard DAMSystem
software provides seamless archival record of
environmental conditions.
