Temperature/RH Smart Sensor (S-THB-M00x) Manual 

11427-M MAN-S-THB 

The temperature/RH smart sensor is designed to work with smart sensor-compatible HOBO® 
data loggers and stations. All sensor parameters are stored inside the smart sensor, which 
automatically communicates configuration information to the logger without any 
programming, calibration or extensive user setup. 

Specifications 

 Temperature 

RH 

Measurement Range 

-40°C to 75°C (-40°F to 167°F) 

0-100% RH at -40° to 75°C (-40° to 
167°F); exposure to conditions 
below -20°C (-4°F) or above 95% 
RH may temporarily increase the 
maximum RH sensor error by an 
additional 1% 

Accuracy 

±0.21°C from 0° to 50°C (±0.38°F 
from 32° to 122°F); see Plot A 

±2.5% from 10% to 90% RH 
typical to a maximum of ±3.5% 
including hysteresis at 25°C 
(77°F); below 10% and above 
90% ±5% typical 

Resolution 

0.02°C at 25°C (0.04°F at 77°F);

Bits Per Sample 

12 10 

Drift 

<0.1°C (0.18°F) per year 

<1% per year typical 

Response Time 

5 minutes in air moving 1 m/sec 

5 minutes in air moving 1 m/sec 
with protective cap 

Operating Temperature Range 

-40°C to 75°C (-40°F to 167°F) 

Environmental Rating 

Weatherproof: 0 to 100% RH intermittent condensing environments. 
For best results, the temp/RH smart sensor should be mounted inside 
a protective enclosure, such as a solar radiation shield. 

Housing 

PVC cable jacket with ASA styrene polymer RH sensor cap; modified 
hydrophobic polyethersulfone membrane 

Sensor Dimensions 

10 x 35 mm (0.39 x 1.39 in) 

Weight 

S-THB-M002: 110 g (3.88 oz);  
S-THB-M008: 180 g (6.35 oz) 

Number of Data Channels* 

Measurement Averaging Option 

No 

Cable Lengths Available 

2.5 m (8.2 ft); 8 m (26.2 ft)

Length of Smart Sensor 
Network Cable* 

0.5 m (1.6 ft); 6 m (19.6 ft) 

 

The CE Marking identifies this product as complying with all relevant 
directives in the European Union (EU). 

*  A single HOBO station can accommodate 15 data channels and up to 100 m (328 ft) of smart sensor cable (the digital 

communications portion of the sensor cables).
