Analog moisture and temperature sensing combined with dual-channel on/off control for both humidity and temperature can be found in the HS2000C sensor/controller platform. As a result, it opens up new OEM uses for accurate, low-cost control. High and low limits are factory-embedded in the device according to user requirements. The controller can be configured for direct or reverse action. Its two outputs will equal either zero or the supply of 2 to 5 V. Optional proportional control, LCD display, and various packaging styles are available. The unit is accurate within ±2% and operates from ­30°C to 100°C. The dime-sized unit costs under $35.
