Pipeline design, probe holder, new flange pipe sleeve, unique sealing rubber ring design, adjustable probe position, safe and firm Wall-mounted design, probe holder: unique design to prevent adjustable probe position, safe and firm. PC plastic, the product adopts heat-resistant, durable, high-quality PC housing that is not easily deformed, and the high-temperature probe can measure the temperature up to 125 (not long-term high-temperature environment) High-quality shielded cable, built-in 48 metal shielding layer, PVC skin, copper tin-plated pins, metal sintered filter cap, easy to clean, detachable, better air permeability and dustproof effect Model: AM2305 Measuring range: temperature: -40~+80C, humidity: 0~99.9%RH Accuracy: temperature: +/- 0.3, humidity: +/- 2%RH (25) Resolution: temperature: 0.1C, humidity: 0.1%RH Attenuation value: temperature: less than 0.1/year, humidity: less than 0.5%RH/year Sensor: Capacitive humidity sensor Working voltage: DC: 3.3-5.5V Plastic weight: 77g Temperature and humidity sensors mostly use temperature and humidity integrated probes as temperature measurement elements to collect temperature and humidity signals, and undergo voltage stabilization filtering, operational amplification, nonlinear correction, V/I conversion, constant current and reverse protection, etc. After the circuit is processed, it is converted into a current signal or voltage signal output in a linear relationship with temperature and humidity, or it can be directly output by the main control chip for 485 or 232 interface. Colour: white Material: plastic Size: 99.9 x 16mm Package Contents: 1 x temperature and humidity sensor probe 1 x bracket Only the above package content, other products are not included. Note: Light and different displays may cause the color of the item in the picture a little different from the real thing. The measurement allowed error is +/- 1-3cm.
