ZTP-188MA - Thermometric IR Module


The ZTP-188MA 1 x 8 IR module is used for noncontact surface temperature monitoring. This thermopile IR module presents the temperature compensated 8 linear array outputs via I2C with optics (Silicon Lens). It can also provide compatibility with the customer’s device without the need for recalibration. The ZTP-188MA uses 4-wire connections: two signals for I2C output, single power supply and ground. The sensor is fully calibrated with a wide object and ambient temperature range. Lens for different field of views are available on request.
