Pipeline design, probe holder, new flange pipe sleeve, unique sealing rubber ring design, adjustable probe position, safe and firmWall-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 effectModel: AM2305Measuring range: temperature: -40~+80°C, humidity: 0~99.9%RHAccuracy: temperature: +/- 0.3℃, humidity: +/- 2%RH (25℃)Resolution: temperature: 0.1°C, humidity: 0.1%RHAttenuation value: temperature: less than 0.1℃/year, humidity: less than 0.5%RH/yearSensor: Capacitive humidity sensorWorking voltage: DC: 3.3-5.5VPlastic weight: 77gTemperature 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: whiteMaterial: plasticSize: 99.9 x 16mmPackage Contents:1 x temperature and humidity sensor probe1 x bracketOnly the above package content, other products are not included.Note: Light shooting 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.
