Sensor Products

Renesas’ humidity and temperature sensors offer high accuracy, and lowest power with the fastest measurement response time of comparable devices currently on the market.

The HS3xxx and HS4xxx families of relative humidity and temperature sensors feature a ±1.5% RH accuracy. The sensors offer both digital and analog outputs, supply voltage range of 1.8V to 5.5V and waterproof IP67 options. The HS4xxx offers the lowest power consumption with an average of 0.62µA current at 3.3V (one RH + T measurement per second). In addition to high-accuracy and fast response times, the HS3xxx and HS4xxx family features excellent long-term stability of 0.1% RH per year as a result of a robust silicon carbide construction and an innovative design. This improves useful lifetime and lowers effective costs.
